With this kernel 5.8.0-35-generic #37~lp1907212+2 nvidia gpu is successfully powered down, and idle power consumption was normal at 5-6 watt.

$ cat /sys/bus/pci/devices/0000:01:00.1/power/runtime_status
suspended
$ cat /sys/bus/pci/devices/0000:01:00.1/power/control
auto

On dmesg output there are a lot more `snd_hda_intel 0000:01:00.1: can't change power state from D3cold to D0 (config space inaccessible)` complaints.

I also rebooted at nvidia performance mode, everything is normal but `0000:01:00.1/power/runtime_status` is again suspended. I don't know if it is supposed to be like this but with 5.8.0-31-generic when booting with nvidia performance mode, `0000:01:00.1/power/runtime_status` is active.
