Wait a minute, I don't even know what version of macOS you are on now.Ah, tell me if this sounds right @trs96:
1) put the Nvidia card back in
2) uninstall Nvidia web drivers
3) power off & put AMD RX580 back in
4) verify the old system boots (no gpu trouble)
5) copy that old config.plist to the new usb efi
6) proceed with fresh install...
