cPanel Backup Easy way to uncheck account to backup

I was wondering if it is possible to comment out the backup files as unchecking the backups could take a long time to get through so I would like to comment out the backups that I don't want to be backed up and then uncomment them.

I found /etc/cpbackup-userskip.conf but here I neewd to add all the users, doing that would it cause any problems
