Maybe you mean the Focus Mode?
No.
You know how the "do not disturb" mode works on a pure google phone, right?
You can disable tones for all notifications but the calls. For example this could be usefull if, like me, you have to be reacheable during the night for work.
You can set your phone rings for ALL calls, for starred contacts only or none, where notifications from all apps will be muted.
On Xiaomi phones, this, never worked.
If you activate the do not disturb mode, and if you choose to set the phone to ring for ALL calls (in other words, you set the phone to ring just for every calls and nothing else), the phone will ring for everything. Messages, emails, telegram, whatsapp.
This is why i cannot use a xiaomi phone for work. I cannot sleep without notifications every minute....
Don't ask me to disable data
I wonder if this "bug" (even if developers say this is a feature and not a bug) is still there.....
