Why are you disabling HA? Do you perhaps mean disable sync?

 

I think the wiser move would be to disable Automatic Sync for the Device Group, make changes to the standby, then fail over traffic to that device and have the application groups test. If the tests fail, switch back to the other unit that didn't have any changes. If the tests pass, sync the changes to the now standby unit.

 

Save a UCS from both devices before and after changes, while you're in there...
