SS addicted to screen time

Our SS (7) stays with 2-3 days out of the week. We also have an ours baby (8mos).

For the longest of time, SS has been addicted to his iPad, tv, play station, anything with games or videos. I don’t really dictate on what he does, I let his dad do that and he’s on the screen maybe 80% of the day. (Genuinely shows signs of an addict, like withdrawal symptoms and all when we take it away). I recently intervened and took the iPad away during meals because I do not want ours baby getting used to screen time during meals.

Our living situation: we have a 2 bedroom home, 1 room is us (mom dad and baby) & 2nd room is for SS and my office. We have since moved my office stuff out the kitchen area as we plan to move ours baby in there by the time she is 1. I do not want a tv & or any screens in there.

Is it okay for me to remove the tv (altogether) and move the play station to the living room? I would like for the PlayStation to be used for privileges only, not accessible at any time. This would reduce SS screen time by ALOT as he always watches tv in his room. (He also has to have the tv on throughout the night to sleep) along with a nightlight and a lullaby. I would like to reduce these things also because ours baby doesn’t sleep with either and also our electricity bill is a lot higher than it should be due to this specific need. I truly don’t think he needs a nightlight PLUS tv PLUS lullaby for him to sleep.

I think this will be good for him as it force him to go outside in the living room or actually do other activities like reading, playing board games, going outside, playing with his sibling vs gripping the remote and watching tv for 4 hours straight.

What do you guys think?
