I had the same problem on a GigaByte Series 8 board. The fastest solution is to use a Mac ID which has no internal graphics card (I have a Radeon 580 and disabled the IGD in BIOS). I used clover configurator, load the config.plist from the boot drive's EFI folder and set in SMBIOS the model to iMacPro1,1. After reboot everything worked.
