Amazfit Watch faces

Does anyone know of a way to increase the time that the screen stays lit? On my Amazfit Falcon, the maximum amount of time is 20 minutes. I would like to at certain times extend that time to 1 hour or more. I am not concerned with battery consumption when I choose this setting.

Thank you in advance.

Thank you for responding. I would like to keep the main watch face active and not have it go to screen off styles. Right now I have always on display set to All Day. It keeps switching to the screen off style after 30 seconds.

Thanks in advance.
