Seems as if the older Intel Arc GPUs are supported.

I would give it some time and a newer kernel will comes to TrueNAS, then it will require HexOS to also update their system to be tested and released with that updated TrueNAS Scale Version, it will be a bit most likely, for the newer ones.
But your A380 should be supported per these post.
