You probably want to look at what you can do with the slurmdbd database
and associations. Things like GrpTRES:

https://slurm.schedmd.com/sacctmgr.html

# GrpTRES=<TRES=max TRES,...>
#     Maximum number of TRES running jobs are able to be allocated in
# aggregate for this association and all associations which are children
# of this association. To clear a previously set value use the modify
# command with a new value of -1 for each TRES id.
#
#  NOTE: This limit only applies fully when using the Select Consumable
# Resource plugin.

Best of luck,
Chris
