Does ffmpeg or NVDEC (nvidia decoder) support YUV444 video input?

I tried feeding an .h264 video with YUV444 color format to ffmpeg in hardware decoding mode on a GTX 1660 and it looks like this color input isn't supported. I get an error in the get_hw_format function.

On https://developer.nvidia.com/video-encode-decode-gpu-support-matrix it does not say anything about h264 color support on NVDEC. How can I know if I can decode YUV444 using NVDEC?

And if NVDEC supports it, why doesn't ffmpeg do it if it uses it?
