Workaround for the add-on not being available
This worked for Ubuntu Server ARM
https://microk8s.io/docs/addon-gpu#microk8s-121-12
https://gist.github.com/neoaggelos/a4244cc92f76599b0d8febfeae3a28a8

However, there is a customer that requires this on Ubuntu Core ARM
I would believe these manual steps will not work on Core that needs everything to be a snap
