And what do you mean "share your docker compose for the Jellyfin container"... How would i go about doing that? 

I was assuming that you were running Jellyfin on a separate device.

I'm assuming your NAS has some sort of UI for configuring the Jellyfin container.  Did you make the iGPU available to the container?  It isn't able to access the GPU.
