Turning off siren in arm (stay) 'mode'

I’m trying to figure out how to turn off the siren in “arm (stay)” mode, but there’s no such option. Has this been implemented yet? I wouldn’t mind setting the siren to a toned-down beep either, but that option isn’t available either.

Has anyone experienced this as well?


P.S. I’m using Aeon Labs ZW080-A17 siren
