I just need to know the correct bootflags in case there is WhateverGreen interference, and the correct ig-platform-id to enable the GPU correctly. Would you happen to know this information?
I had an RX 580 and the HD 4600 working in this way on my previous build which worked fine with multiple monitors, so macOS can handle it.
ig-platform-id is 3E9B0007 for UHD 630 non-headless.
HD 4600 may have worked because you were on an ancient system definition that didn't utilize IGPU the way more modern iMacs do.
