Does the Do Not Disturb mode ring when the phone is turned on?

If you use a vivo mobile phone, after the Do Not Disturb mode is turned on, all incoming calls, messages and software notifications are muted except for the "Do Not Disturb" contacts, and you can also set the Do Not Disturb mode to be turned on automatically for a certain period of time. If you allow reminders-notification and status bar-apply notification management-select software-select message type-turn on Do Not Disturb, you will receive notifications and reminders in do not disturb mode.

Note: In "Do Not Disturb" mode, the alarm clock will still ring.
