Notification vibration of Nougat system

Yes, there are 2 ways to achieve your goal:

• Hold the notification and select Show notifications silently, then press Done


• Go to Settings -> Apps -> choose the app you want to mute -> Notifications, then toggle Show silently option.

You have to do this for every app you want to be silent, as notifications are handled per app. This will prevent them from making sound, vibration or peeking.
