BOINC not using the GPU (Docker)

Does someone know the reason why einstein@home is not using my gpu?If I use BOINC on my Windows system it uses my GPU right away but in Docker on Unraid I never get GPU tasks.

I have a Quadro T600 in the Unraid system.

The settings work fine in the Plex docker, there it uses the GPU for transcoding if required.

Thank you.
