Set "Evaluate this account against territory rules on save" in a Flow?

We are evaluating Enterprise Territory Management and see there is a setting on the page layout called "Evaluate this account against territory rules on save" but it seems when I inline edit this doesnt work. How can we get this to work?

Also, Is there a way to trigger this or make sure this runs when a flow or process builder does some work on the account record as well? How about via a trigger?

Thanks for the help.
