Hardware transcoding ARM64 (DGX Spark)

Plex Media Server

Server Version#: 1.43.0.10492
Player Version#: N/A

Hi! I recently moved my PMS to an Nvidia DGX Spark. I run PMS through the docker image (linuxserver/plex). While it works fine, I am unable to select hardware transcoding option in the server settings. When I run docker exec -it plex nvidia-smi I get the expected Nvidia ouput.

So I was wondering, does Plex support hardware transcoding on ARM64 CPUs or is it an oversight that there are now devices that support NVENC on ARM64 too? Is there some way I can try to force the hardware transcoding setting manually?

Perhaps its a different issue
