CPU priority for Docker vs VM

[Jezper]

I'm running Unraid on an i9-9920X 12 core CPU. On the server I have:

 

Windows VM, doing calculations 24/7 that takes up 100% CPU power (of the cores I give it).

Plex Media Server Docker.

 

To be able to do a 4K HDR transcode with Plex, I have to reduce the number of cores for my Windows VM to 6 cores. But since Plex only needs these recourses once in a while, 50% of my CPU sits idle most of the time.

 

Therefore I wonder if there is any way to dedicate 11 cores to the VM, but let the Plex docker have a higher CPU priority, so it can use as much CPU power as it needs, when it wants to, and let the VM have second priority when the docker needs power?
