That's just what I've been doing after deleting Instagram from my. phone. I can't trust my evening dopamine-seeking behaviour with the phone app, but there's much much less stickiness in the browser.
Have you tried just not using a smartphone? I have a flip phone I take with me and leave my iPhone at home for things that need it. Otherwise, I carry my laptop/tablet everywhere. If I need to check my social media or email I have to sit down and deliberately do that
