NVIDIA Ampere correctly configured but does not enter D3

I have recently setup the discrete NVIDIA Ampere I have (NVIDIA GeForce RTX 3060 Mobile) so that the system can offload work to it (as depicted in  depicted in https://wiki.archlinux.org/title/PRIME). This works, so that should I execute

__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep "OpenGL renderer"

It comes back with "OpenGL renderer string: NVIDIA GeForce RTX 3060 Laptop GPU/PCIe/SSE2", otherwise (without the env vars) with the integrated AMD Radeon device. So far so good... but I cannot get it to sleep. Besides: should I run nvtop, I see that the only process making use of the GPU is Xorg (I guess this is the reason for the GPU staying awake).

Does anybody have any suggestion on how to fix this? Thank you very much!
