How can I disable 1 gpu from mining when I want to use it for gaming? I am using xmr-stak. Cards are Nvidia 1080 ti and 1070 ti.

I just need two seperate xmr-stak folders with different config files correct?

One will be setup to mine from CPU + Both GPUs

One will be setup to mine from CPU + Second GPU only (comment out the GPU I don;t want mining??)
