Windows 10: How do I always allow an app to make changes?

Go to:

Control Panel\ User Accounts and Family Safety\ User Accounts

Click “Change User Account Control Settings”

You should now see a vertical slider that governs what UAC does. At the top should be “Always Notify,” and at the bottom should be “Never Notify.” Slide it all the way to the bottom if that the setting you desire, then reboot. Windows should never trouble you again.

(Information from here)

N.B. This setting will apply to all apps, not just a single one.

You can use UAC Trust Shortcut for this. Basically it creates a shortcut to the app you want to run that is somehow exempted from UAC. Kind of hacky, but it works.
