With condor_off -peaceful for new enough versions of condor,
the jobs will run to completion but no new ones will start, and
new ones will still be able to be submitted to the queue.
condor_off -graceful (the default) will kill all jobs after
a configurable timeout, by default 1/2 hour.

To block submissions the only way is to just kill the schedd
but this is not acceptable because then you have no track of when
the running jobs have finished.
