Intel 12:th gen Alder Lake CPU not supported with OPENCORE?

I have the intel 12 th gen alder lake cpu, I am currently trying to install macOS Catalina but I get the error

OC: Failed to bootstrap SB NVRAM values - Invalid Parameter, Halting on critical error 

I was later looking at this "guide" and it seems that I need to have dedicated GPU for the 12 gen intel.
Has anybody any input on this?
