Can't clover uefi dual boot separate drive in upgrade bay on 4530s: Skips the Clover installation!

[willpower101]

I have this strange problem on my friends 4530s that I've never experienced on my 4440s.

The UEFI is only ON/OFF in the bios. No Hybrid.

The ONLY UEFI boot options to select are:
OS BOOTMANAGER
EXPANSION BAY

With UEFI clover installed on sata0 (Primary),
and UEFI win10 on sata1 (upgrade bay)

The automatic selection of OS Bootmanager, SKIPS the sata0 UEFI and goes straight to windows upgrade bay.

If I remove the windows 10 in the upgrade bay, behavior is as expected and Clover boots.

If I manually choose UEFI, sata0 boots as expected and clover boots.

If I SWAP drives, sata0 boots as expected..... but with WINDOWS in the primary bay.

Why in the world is it skipping my clover drive when it's in the primary bay?

It is always hybrid (with CSM).

The automatic selection of OS Bootmanager, SKIPS the sata0 UEFI and goes straight to windows upgrade bay.

Of course.
You have to rename bootmgfw.efi to bootmgfw-orig.efi.
