Hardware Transcoding for Docker in WSL2

Recently started messing around with Docker (no Docker Desktop) within WSL2 so new to this type of build. Pretty much got everything working as I expected with the exception of hardware transcoding.

When running my initial docker-compose.yml and the section:
devices:
- /dev/dri:/dev/dri

got the error:
error gathering device information while adding custom device "/dev/dri": no such file or directory

In reading about WSL2, I read that the GPU is virtualized as /dev/dxg so tried changing the docker-compose.yml to:
devices:
- /dev/dxg:/dev/dri

This ran successfully but I only see software transcoding, so wondering if anyone has gotten this working with hardware transcoding enabled and/or if this is possible

I don't think it's possible
