Focus on making something, you'll be too busy (or maybe just too tired outside of it) to spend time arguing with people.
More generally, avoid "idle hands", which is a poor phrase since arguing with the internet is a very idle thing to do despite lots of hand movement whereas reading say a book of philosophy from the 1600s is probably going to be better for you and involves less hand movement.
Or like another comment says, wait. This is probably your most realistic option anyway. It tends to get old as you get old too. Sometimes it's the same arguments (sometimes with the same people, but even without that) get old, or eventually stop mattering to you on an alief level, regardless of your "it does/doesn't matter" verbal belief level. Sometimes it's because you advance your own thinking and then find yourself at a place where it's just hard to find people with the same background context, so when you do engage others before you can argue about what you actually want to argue about, you first have to futilely attempt to close the inferential distance they lack because they haven't read the books you've read or whatever. It gets old.
As a remark on the top comment, I got into Taoist philosophy quite a bit in my teens. It helped (helps) not being attached to outcomes or having a "need" to argue apart from it being pleasurable, it helps cultivate "it doesn't really matter" views, but it didn't stop me from entering a very argumentative phase anyway. It's also fun to just discuss things, but the very act of bringing topics and edge cases and implications thereof up for discussion even if you don't strongly hold a conclusion can still comes across as "argumentative". Oh well.
Are these one-on-one chats or group chats you're mostly in? As a word of caution, arguing with people one-on-one is a great way to eventually not chat with them at all in the future. (On the other hand not arguing with them is no path to long term conversation either. Not everyone is a creature of the internet.) Sometimes you'll find that rare buddy who seems to indulge in your arguing, and can change your mind from time to time too, and they exist, but then some of them are fighting what they perceive to be an attack on their ego rather than what you think is an ego-free discussion trying to reason about a topic and so regardless of the intermediary results the final result of no longer having conversations at all is the same.
