Msfs2o2o and 3rd party push back

Can anyone help me out to where I can shut down ATC automatically calling out for a pushback where I can use a 3rd party pushback? What needs to be disabled?

Disable radio comms in assistance options at the main menu. You can re-enable them on the toolbar again or in the game menu, but this must be done after pushback. They should exclude pushback from this assistance as it´s a real pain.
