Proxmox -> ovm6 vm -> Plex docker - is igpu hardware transcoding possible?

Howdy, my first post in this wonderful forum.
The computer that I am using is a small chinese intel minimachine with a 6 core laptop cpu with a 630 igpu.
As the title states I am trying to get hardware transcoding by the igpu in a docker container to work. Its hosted as a docker container in a OMV6 virtual machine, which is hosted on a proxmox server. I get the igpu running inside the omv6, but cant load it in the docker container. (I am using the device dev/dri:dev/dri line in docker. )
First of, is it possible? Havent seen any guides that describes the procedure.
When using modprobe i get error messages that I am missing the i915 module, but I cant the the module to build due to some errors that are supposedly patched in a later kernel patch. However if its not possible anyhow, then I am not going through all the hassel of trying to get it to work.
So have anyone succeded with getting a passthrough to a program running in a docker container inside a vm hosted on proxmox?

Kind regards.
