Suppressive fire is not an incredibly complex concept. It's point a FA gun at someone, hold the trigger, and keep it relatively steady so that it shoots in an area. It doesn't even really require aiming. So, I would say no. The pilot is built on a drone to understand combat to some extent, and although the reasons for suppressive fire are complicated, the actual act of doing it is not. The pilot doesn't really need the reasons, so I would say it's perfectly capable of doing the action.
