Rather than configure it to only run one job at a time, you can use job dependencies to make sure only one job of a particular type at a time. A singleton dependency [1, 2] should work for this. From [1]:
#SBATCH --dependency=singleton --job-name=big-youtube-upload in any job script would ensure that only one job with that job name should run at a time.
