You can get a phone pureley for work, and turn it off outside of working hours. As with your elderly parents, it might be a good idea to tell them to call you instead of text for important/time-critical things. Non-important stuff can go to Whatsapp, and you check infrequently. I myself gotten a non-smart feature phone as secondary device with a MultiSIM - i.e. both my smartphone and my feature phone ring when I get a phone call, and I can take it on any device. I also told my close contacts to call instead of text as I might be without smartphone. If I want focus time, I turn off the smart-phone or leave it at home.
