Take a look at the Upgrade Notes section here for how to enable nvidia drivers in the BETA
I am also having an issue with my P2200 and Tdarr.
Tdarr wont load with the NVIDA card selected but will load when I select the iGPU.
lspci shows both my igpu and the p2200.
I am on dragonfish the newest one.
This solution worked for me: FIX: NVIDIA Pod in Crash-Loop on TrueNAS Scale k3s Setup
This will only work on dragonfish and and the kubernetes apps backend, not Electric Eel and docker.
