Bit similar to a previous post I made but I'm making this because I feel like a guard panel should be usable without the driver automatically closing the doors or driving off whilst you still have yours open. A simple fix that wouldn't require coding a whole guard mode would be to do what was done on the Northern route and also the Seaford route with the 313, add a door control MCB into the cab of the train, this way you can switch it off, the driver won't interfere and you can actually be in control of the doors and departures. This should be added also to upcoming routes with guard panels
