How to turn off specific GPU?

I found a way to do it through nvidia-smi. I just didn’t know what drain mode meant.

sudo nvidia-smi -i 0000:xx:00.0 -pm 0

# changing gpu to draining mode (power idling)
sudo nvidia-smi drain -p 0000:xx:00.0 -m 1

#enable again persistance mode.
sudo nvidia-smi -pm 1

This hides the selected gpu from other applications, and only uses the gpus that are no in drain mode.
