How to disable a PeopleSoft Workflow?
How to disable a particular PeopleSoft Workflow Activity/Event?

This solution is applicable for PeopleTools version 8.4x including 8.44, 8.48, 8.49. I am not sure about other versions of PeopleSoft and I firmly believe the other versions of PeopleTools will also behave the same way. There are three methods that we could do it.
Method#1 - The Application Designer Way:
In Application designer, we can Open and turn off the Active check box for each Activity, event.

Method#2 - The backend way (database update):
Alternatively, the same result could be achieved by turning off the Active flag record in PSEVENTDEFN record. This would be the most preferred way to prevent workflows getting triggered for a short term for example like the day when mass data updates through PeopleSoft CIs. Once the data updates are over the Active flag can be turned on again by a record update script.

Method#3 - The PIA way:
Navigate to PeopleTools -> Workflow -> Defaults and Messages -> Set Workflow Defaults
Then uncheck the worklist and email boxes. However, this will disable all the workflows rather than just one particular event or required event(s).
