Mac Os Big Sur, Kexts, Opencore advice

Hello,
The guide


says:
15. Navigate to /EFI and apply necessary kexts, SSDTs.

How do I find out what Kexts and SSDT's I need to apply?
Is there a database or some sort of guide?

I have the setup listed in my specs using the motherboards onboard gfx

Many thanks for any help you can give!
