For "Do not disturb" (if this is what you ask) you can configure it in device settings: Sound > Do Not Disturb > section "What can interrupt do not disturb".
It seems that I used that before, and it had those options.
It seems that I left that option and went to the Mute afterwards.
One of the reasons was that I needed to manually set up Do not disturb through many buttons, when I can Mute with two button presses. (I can set a schedule but it changes day to day so it's not convenient.)
So Do not disturb became less convenient to be used.
"Do not disturb" option should be available as a quick setting tile, which is more complicated to activate from a button combination, but not too hidden in the device settings.
In home screen or in the toolbar I pull down from the upper edge of the screen?
Swap screen down from the top of the screen - like when you want to see a notification: different devices acts differently, in some you have to swap from upper-right to see the tiles. You can also edit the tiles to add, remove and re-arrange, in order to have the ones you use more often in the first page.
