Struggling to Remove NVIDIA GPU and Add Intel GPU in Plex – Help!

I've been trying to add an Intel Arc A310 GPU to my Plex container that already has an NVIDIA RTX 1660 Super working without issues. However, recently, I decided to remove all references to the NVIDIA GPU for troubleshooting because I'm having constant issues with the Arc GPU. The strange part is, even after trying to remove the RTX GPU, it still shows up in my Plex server whenever I restart the container.

I added "/dev/dri" to include the Intel GPU, and I deleted the runtime: nvidia line along with the environment variables for NVIDIA_VISIBLE_DEVICES and NVIDIA_DRIVER_CAPABILITIES. Despite all this, the NVIDIA GPU is still the only one visible in my Plex container.

I also attempted to change GPUs for my Immich and Tdarr containers, but they still only recognize the RTX GPU, not the A310. Just to clarify, my host system is Debian 12, and I can see the Intel GPU listed without issues using hwinfo, systemctl, and renderD128 alongside card0 and card1 in /dev/dri. What am I missing?
