How to deactivate all Omniscripts?

I'm trying to re-seed a sandbox that contains omniscripts.  OwnBackup complains, "You can not add, update or delete Element records for an active OmniScript record." 

So, since I want to DELETE them all to re-create them, is there a script that will deactivate them all? 

Or assuming each one has an "isActive" field, anyone know which objects to check?
