what version of BIOS are you on?
Perhaps patching the files from the latest BIOS you're running would help.
Upgrade to latest BIOS, no need to set the DVMT with EFI_Shell, there's new kexts that will fix that. I'll make a new boot pack for it.
Reset BIOS to default, then set UEFI, AHCI, disable TPM and secure Boot.
Extract the raw files with F4 while booting into Clover.
Compress and attach /EFI/Clover/ACPI/Origin here for patching
