I think you get me wrong...
Use the iGPU (QuickSync - this is also Hardware transcoding) not the CPU (this is Software transcoding), simply install my Intel-GPU-Top Plugin that will enable the iGPU and then you have to add a device to the Plex/Jellyfin/Emby container template with the path '/dev/dri' and remove the Nvidia entries:
That should be no problem as long as you don't transcoding only 4K files (but 8x 4K transcodes is also too much for the P2000).
This is completely off topic here, eventually start another thread and mention me there, or look for something like Intel iGPU and Plex, you even can install the GPU Statistics Plugin from @b3rs3rk and see the usage of your Intel iGPU.
