I don't have (diagnosed) ADHD, but this keeps me sane:
1. mute all @here or @channel notifications. Those are almost never critical. If somebody needs you to do something, they'll DM you.
2. pick a handful of channels that are important and mute all others (in that they don't show up as having unread messages). Those are the channels that you'll want to read all messages in.
3. Block 1-3 daily calendar entries with 15 minutes in them in your calendar for Slack time. This is the time where you will read the messages from 2. and respond. Feel free to extend the time blocks if you need to if it's up and you aren't done. You'll look at channels in 2. outside of these time blocks.
4. If there is something urgent going on (ie production outage), you'll deviate from this and that's fine.
