Power off discrete GPU while not in use? (lemm.ee)

Hi guys!

I purchased a few months ago a new AMD PC, with a 7700 CPU, 32GB of RAM and a 7800XT GPU. I've noticed since, that my electric bill has been increased (compared to when I used an Intel i7 6700 with a 1070 GPU), I was wondering, is it possible to use a hybrid GPU setup kinda like laptops, where the iGPU from the CPU is activated for normal tasks, and the discrete GPU is only activated on demand? Would the GPU be unpowered/sleeping in the meantime?

....all this from a Linux perspective, I'm running Nobara 40.

Thanks!

Lol...I didn´t consider that. What crypto can you mine that can give you at least some cents back? Sorry for the offtopic. Yeah I'm in the process of setting up some sockets with zigbee switches and power metering. I'll install the one for the desktop soon, and start measuring more accurately. Is there a way to know which GPU are you using at any given time?
