Turn off all notifications. Turn off all badges. Change default text tone and ring tone to silence (make or purchase a ringtone of silence). Set custom ring tone for your partner or other key people (you will always be happy to be interrupted by) to whatever sound you would want in emergency. At this point, only those you would welcome interruption from can get your attention. For meetings, toggle phone to silent, so even the custom ring people won’t make noise. If you “must” be reachable in real time for work, consider scheduling DND for all hours outside work hours. You can, on a contact by contact basis, designate individuals as able to dial through DND for emergencies.
