Thanks, I have yuv420p and yuv444p working now.

For P010, I tried using:
ffmpeg -loglevel debug -v verbose -hwaccel cuda -hwaccel_output_format cuda
-i noise.mp4 -vf format=p010,hwupload,nlmeans_cuda=20,hwdownload nlmeans.mp4

and I get:
[Parsed_format_0 @ 0x558bf0ff6bc0] auto-inserting filter 'auto_scale_0'
between the filter 'graph 0 input from stream 0:0' and the filter
'Parsed_format_0'
Impossible to convert between the formats supported by the filter 'graph 0
input from stream 0:0' and the filter 'auto_scale_0'
