Sure, but these are also children who all live together in the same house. I can't imagine it will improve behavior, not to mention sibling relationships, for one child to be denied an activity that the others can still enjoy. I'm picturing the oldest being told no screen time, and also having no one to play with because the siblings are on screens. And would you also ban the oldest from watching the others play? How would you enforce that without isolating the oldest?
Setting some global parameters seems best, whether that's time limits, earning through behavior, specified consequences for issues, etc.
