Nvidia-smi cannot find GPU on mini PC with muxless config

Hello
Trying out a new mini PC with an nvidia 1650 but when running nvidia-smi the GPU is not discovered (“No devices were found”). I see in the BIOS that the selectable graphics is “muxless” and cannot be altered. Used prime-select to set nvidia and prime-select query shows that it worked.

Any help much appreciated.

The nvidia driver doesn’t like your board
NVRM: GPU 0000:01:00.0: RmInitAdapter failed! (0x26:0x56:1253)
Please check for a bios update, otherwise, so far known working are drivers <=460, 470.54-470.82. You might also try the open sorce modules.
