Hi pkursawe,
Let's say NavBarCommand is used to navigate to another page while AppBarCommand can be used to execute some command.
Disable AppBarCommand can deliver a information that the app has such function but currently it is not available. However if you do not want the user navigate to a specific page, why not directly hide the NavBarCommand or do thing with the NavBarCommand?
This also could be a Customer Wish and I will submit to seniors for you.
