I need help adding a perk to a custom character that makes them unable to prototype items.

I'm just getting into making a custom character but I feel I need help, or to be pointed in the right direction. One of their main perks which I have absolutely no idea where to start with implementing into the game is they cannot prototype any item, meaning they must be standing near a research station to craft any science/magic item even if they have already crafted it in the past. If anyone can help me or point me towards a good tutorial I'd be very greatful.
