How to set up iOS 13’s Do Not Disturb mode — Apple World Today

With Do Not Disturb in iOS, you can silence calls, alerts, and notifications that you get while your device is locked. You can also schedule Do Not Disturb and allow calls from certain people. The feature is designed to help users stay more focused while they’re behind the wheel of an automobile. 

Do Not Disturb limits notifications on demand or during a schedule you set up. Along with limiting or muting notifications, it can also reply to contacts who send you messages while you’re driving, giving them a heads-up that you’re on the road.
