How to access macOS efi when changes to PC occur

So I recently upgraded my GPU from a non Catalina compatible GPU to an RX 5600 XT. Now the dumb thing is that I forgot to edit my macOS’s efi so that I can use the GPU for display and now that I’ve already put it in, macOS no longer boots. Is there a way to access macOS efi without having to reinstall the whole thing again?
