I am on a Gigabyte Z87MX-D3H, I had something like 30 boot entries, I was getting really confused.
I do confirm that flashing the bios to the latest version F7 fixed the issue.
Thank you, super helpful thread.

6. When your have removed all entries that are not physical hard drives, type
Code:
exit
and press the return key. This will get you back to the main Clover screen. At this point, I would choose restart from the Clover choices and enter the BIOS to check if your work was successful.​
After checking in BIOS three (Edit: it was four, or three extra) instead of one UEFI option remain. I go through the same procedure of removing the extra options, but everytime the persistent boot options reappear in the bios. Any suggestions on what to do about that?​

Are they for three different partitions?

Thank you Vulgo.

I was about to start installing Mojave on an SSD. The SSD had been erased and reformatted in Disk Utility on a different machine, so it was supposedly empty (and in one partition). This was was the only internal hard drive connected. I was starting up from a Flashdrive made with UniBeast.

I've now installed Mojave and everything seems in good working order. I'll try again, starting up from the SSD without the Flashdrive connected. Of course, after installing Mojave, now there are many options in Clover (FileVault Preboot, Mojave install preboot and a Recovery Partition, besides the one that is the correct Mojave one on the SSD. Do I really want to remove all those (well, not the Recovery one, I am sure)?

Preboot and Recovery are part of your macOS installation (they are also APFS volumes on a single container partition with the root volume), you can hide them from the Clover menu e.g. using Clover configurator

UEFI may generate 'UEFI' firmware boot menu options for any partition with an EFI folder, it's how it boots from removable media for example. Regarding post #1 the device path for these firmware-generated options won't necessarily start with HD in order to point to a physical disk. Options starting with HD are a short-form device path, firmware matches them to the full hardware device paths for whatever devices are connected at boot e.g. by partition UUID

I think the options you were originally trying to remove were added by Clover, it does that if you press a certain function key.

Clover shows four drives with the following texts:

"Boot Firevault Prebooter from Preboot" (icon shows APFS)
"Boot MacOS Install Prebooter from Preboot" (icon shows APFS)
"Boot MacOS from SSD_1" (icon shows APFS)
"Boot Recovery from Recovery" (icon shows Recovery)

And here's a screen photo from the Clover UEFI Shell:

Options 01 and 02 are clearly on the SSD (main drive: a Kingston branded SSD), while options 00 and 03 do not reveal where they reside, at least not in plain text for humans.

Option 01 obviously corresponds to "Boot MacOS from SSD_1" as it's shown as an UEFI on the Kingston drive
Option 02 must correspond to "Boot Recovery from Recovery", I suppose
Options 00 and 03 I guess are the two Prebooter options

Notice the variable "Optional" - it says "N" for No on options 00 and 03, whereas it says "Y" for Yes on options 01 and 02.

I assume this is how it should be - and that I don't need to try to remove any of those four options. Is my assumption correct?

One more (related?) thing that puzzles me is this: Earlier, when I was booting up from the UniBeast-created Mojave install Flashdrive, it said Clover v.4674, but now when I boot from the SSD it says Clover v.4769. Well, at least it's newer, but I am surprised that the two are not the same version of Clover ???

All as expected.

Option 1 is UEFI boot from the fallback path /EFI/BOOT, option 2 is legacy BIOS boot (BBS = Bios Boot Specification) from the PMBR. Options 0 and 3 are intended for Apple EFIs, they point to boot.efi on the 'Preboot' volume, the specific APFS volume is described by its UUID in the VenMedia path.
Notice the variable "Optional" - it says "N" for No on options 00 and 03, whereas it says "Y" for Yes on options 01 and 02.
It may be there is "optional" data attached to 1 and 2 but not 0 and 4.

No action required as long as Clover is starting when you expect it to.

Shouldn't be a problem.

My bootoption program may provide more information.

Why does it feel Clover is somehow embedding itself into the bios? I had to reinstall OSX due to migration issues with permissions and ownership. I created a clover boot stick with OSX on it. I go to reboot and the stick would not show up in the boot options. So I tried everything, resetting bios even as far as taking out battery. So I boot again and the normal disk I boot clover from finally booted bit whats weird is the version number is wrong. I was using v3766 or somethung like that but it showed v32xx ????? WTH is clover messing up out bio or what?
