tldr; mute everything, also, you can just get another job
I only use slack on my work laptop (no work-related anything on my phone, or any other device), and mute absolutely every channel that is not with my immediate team, and I set times during the day when I check muted channels (once or twice a day), depending on your job title, that might not be viable, but if it is, I highly recommend it
if you are at a position that doesn't allow that, that's kind of the reason you get paid what you get paid, you might've heard that "engineering's all about tradeoffs", but it's really life that's about tradeoffs, you either choose to make a lot of money, or spend time with kids, you either choose to work 80h/w or to have hobbies... my point is that you have control over your life, maybe not complete control, but you can get another job, or accept that the way your life is because of the choices you've both made, and continue to make
