AMD Radeon RX 550 - 560 injected with Opencore macOS Big Sur

I have installed macOS 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?
