"qmod -d" would be the way to go. Just wait for the existing jobs to finish,
and qmod -e once the node's ready for jobs again. From the man page:
-d Disables the queue(s), i.e. no further jobs are dispatched to
disabled queues while jobs already executing in these queues
are allowed to finish.
-e Enables the queue(s).
