I actually have my desktop AMD iGPU enabled despite using a discrete Nvidia card. I use the iGPU to do AI noise reduction for my mic in voice and video calls. I'm not sure if this is really an ideal setup, having both GPUs enabled with both driver packages installed (as compared to just running Nvidias noise reduction on the dGPU, I guess,) but it seems to all work with no issue. The onboard HDMI can even be used at the same time as the discrete cards monitor ports.
