Ran into the same issue, looks like the container is 4 years old and does not have a kernel capable or supporting newer gen intel GPU.
I found this fork that works, change the repository to "ghcr.io/freender/docker-intel-gpu-telegraf:master"
github repo https://github.com/freender/docker-intel-gpu-telegraf
Since moving to the beta I get the following from FCP
Share Library set to use pool cache, but files / folders exist on the ssdraidz pool
This share uses cache pools for primary and secondary storage. I have these ignored for now, just curious if this will be recognized as a valid config in a future release. Or maybe I am doing something wrong.
