3090 Idle Consumption reset

I was about to say how much better 595.71.05 drivers were at reverting my dual 3090s to a lower power state when idle, with my 3090s dropping down to 13w to 15w. Today, however, one of the cards seems stuck at 24w to 30w with zero activity and fan at 0%. I've stopped all running processes and there are no monitor output. Is there any way to quickly, safely reset this without just rebooting all the time?

Power limiting via nvidia-smi is fine but obviously only applies during inference.
