Anecdotally based on my kid (n=1), stopping screen time about an hour before bedtime helps.

However, she still seems wired to fall sleep at a certain time, and we finally decided that fighting biology is a losing battle. The strategy of moving bedtime a little bit earlier each day didn't work at all.

There's definitely no screen time involved anywhere near bedtime. But yes, I'm pretty sure it would not help if there were!
