Unfortunately, I can not do so at this time since I'm not yet at Thunderball's location. (I go South for the Winter.) I'll be able to update before the end of April. Stay tuned.
That being said, did you see
Post #972? I've abandoned the use of the Realtek audio codec. I recommend that you do as well. Follow Post #972 for HS which will get you ready for installing Mojave.
While I have yet to do a production install, if you want to install Mojave now, here's my best guess at the installation procedure:
update all your apps;
update Clover using the latest one in the Downloads > Clover Builds;
backing up your HS system and EFI folder;
create your Mojave UniBeast Installation USB thumb drive;
add MultiBeast for Mojave to the Installation USB thumb drive;
now install Mojave;
after the installation has been completed and you've booted to the Desktop, run MultiBeast:

Install
Don't reboot yet.
Since you have a RX 580 Pulse graphics card:
Run
DCPIManager. If you get this result, skip the rest of these instructions as you have an early, macOS supported Sapphire RX 580 Pulse. If you don't get this result, the proceed, otherwise you are good to go.
Add the FBName = Orinoco and Inject > ATI=true & Intel=True to config.plist which you can do with Clover Configurator or Xcode or PlistEditor Pro (which I use):
Code:

Reboot the computer.
Reboot into the BIOS.
Change BOOT > Boot Options Priorities > Select your installation disk to the UEFI setting for your High Sierra drive.
Note: Always pick the UEFI choice if there are two entries for the same drive.
EXIT to save the BIOS update and reboot.
