Amazfit Watch faces

Good morning,
I have not been able to understand if it is possible to deactivate the display turno on during sleep time.
It is very annoying....
DND doesn't seem to do that function, maybe I'm wrong.
Can you help me?
Thank you

Hi,
You can do that with your amazfit app.
Select profil (in the bottom right) then your device and then Lift wrist to view info. Here you can turn off the display during your sleep time.
