Anyways, on a desktop machine with multiple GPUs, I have no problem using the dGPUs headless (without a display attached) and outputting all video through the iGPU. The multiplexer approach is much more performant since the PCIe bus isn't being used to send data from one GPU to the other, but clearly it is still a shit show because no one understands how to configure the BIOS setting from the OS and maybe do a rescan of the PCIe bus if the dGPU was powered off and then on with the mux state change. This honestly shouldn't be that hard to do...
