I think this is expected - it's not that Slurm is making them available, 
it's that it's unaware of them and so doesn't control them in the way it 
does for the GPUs it does know about. So you get the default behaviour 
(any process can access them).

If you want to stop them being accessed from Slurm you'd need to find a 
way to prevent that access via cgroups games or similar.

All the best,
