How to stop loud notification when arming home mode via schedule?

Set up Ring Home Security and having no issues so far except it keeps waking my kids up. I have a schedule set to automatically arm Home mode at 11pm and then turn it off at 6AM. Problem is that my kids are asleep by 9 and when 11pm rolls around the base station announces VERY LOUDLY that it was armed. Loud enough to wake them and make us jump if we're not expecting it. I can't seem to find a setting to turn this off. Best I can do seems to be to mute the base station altogether which causes a problem because that silences all chirps and sounds across the board. How can I disable JUST the loud notification that a scheduled alarm was armed?
