I managed to get Sidecar working! However the approach I took was to adapt a working EFI for a very similar mobo: https://github.com/cmer/gigabyte-z390-aorus-master-hackintosh — this developer previously was using Clover, but recently switched to OpenCore. My only modifications were to add "agdpmod=pikera slide=0" to the boot-args, although I'm not certain what these flags do
