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!

Well I used to turn off the monitors and leave it running...And the last month I started actively suspending it, and the bill went down. I'm waiting to setup some sockets with smart power measuring features, and I'll have more reliable data on power consumption...but I'm afraid I might need to wait a few days on these.
