Power off NVIDIA GPU

Hello there! I am using an arch-based with Hyprland and GDM as the DM. I have a hybrid graphics setup, with both my Intel iGPU and my NVIDIA dGPU, neofetch is attached. I am trying to get my NVIDIA GPU to power off when I'm not using it, as I have an Ampere card this should be automatic. nvidia-smi detects no running processes. Any help would be appreciated, thank you. i also tried this, no dice: https://wiki.archlinux.org/title/PRIME#NVIDIA. Any help would be appreciated, thanks.
