I'm aware. What I have in mind is that I would completely disable the dGPU. I did read somewhere that it's completely done through software by the driver. API calls are routed to the dGPU when needed. And NVIDIA even managed to disconnect a dGPU *while* a game was running and it instantly went back to the iGPU in some live demonstration of theirs. I also heard here on this forum that it can be done and that the dGPU doesn't matter (though no actual tests). I just need confirmation before I do anything crazy.
