NVENC Error: unsupported device in Docker with Nvidia Container Runtime
NVIDIA Open GPU Kernel Modules Version
570.86.16
Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

Describe the bug
After installing version 570.86.16 of the open GPU kernel modules, I encountered an error when using the NVENC functionality inside a container with Nvidia Container Runtime. The error indicates that the device is unsupported. However, when running the application directly on the host machine, the NVENC feature works correctly.
I confirm that this does not happen with the proprietary driver package.
To Reproduce
docker run --runtime=nvidia --gpus '"device=0,1"' jrottenberg/ffmpeg:4.1-nvidia -report -loglevel debug -f lavfi -i testsrc=duration=5:size=1280x720:rate=30 -c:v h264_nvenc -preset fast -y /tmp/test_output.mp4
