For browsing on PC, there are some pretty solid Chrome extensions that allow you to apply 'anti-procrast' controls that are similar to HN's. Block sites, set max browse time per day, etc. Give "self control" a try (not being snarky, that's the name of the extension).
Phone is easier. Just don't keep your phone in your pocket. If you need it for 2FA, that's cool, just leave it far enough away that you can't mindlessly pick it up and start browsing.
This might sound like dumb advice, but in my experience it really is sufficient. The hard part is retaining the desire to change, and taking the required action every day. If you're like me and you find behavior change to be tough, check out "Atomic Habits" by James Clear. He'll give you a solid toolkit that makes behavior change MUCH easier.
