I have installed mac big sur in a hp prodesk 400 g1 ssf, everything works for me, except the amd radeon rx 550 4GB graphics card, because I don't know how to inject into the Opencore device properties section, when I was using clover it was easy because with fakepciid.kext was injecting the EDID + ati + radeonint + fake pci id ... but with Opencore, I can't manage to inject these properties ... can someone help me?
