I'm experiencing some sound artefacts in Ableton Live caused by strange CPU load spikes when using my computer and got a tip that it could be my dedicated GPU that is causing it. So I wanted to try and connect my desk monitor to the integrated GPU instead and see if there is a difference.

However, I still want to be able to use the dedicated GPU for connection to my TV, where I do most of my gaming. So I was curious: if I were to create a profile in DisplayFusion where I would disable all screens of the dedicated GPU and only have the screen connected to the integrated GPU active, would that completely disable any interaction between the computer/CPU and the dedicated GPU? Or would it require me to either disable it in Task Mananger or physically disconnect it from the motherboard?
