How can I install macOS Big Sur on my M5A78L M-LX3 FX8320 R7 240 (4GB VRAM) + 4+4GB RAM motherboard? Is there an EFI file for it?
 
Have a look at this thread, it may be what you need.

Hi, I tried this but I get text on a red screen and I can't boot.
 
Look in the Bios and see if you can find an entry named 'CSM' (Compatibility Support) or 'Legacy Boot Support' or 'Legacy Option ROMs/OPROMs'. if any of the three named items are present make sure they are DISABLED.

Also check that 'ProvideCurrentCpuInfo' Quirk in the Kernel section of the config.plist isn't enabled, as it doesn't work for FX CPU's.
