Silence TomTom Runner (1st gen) Sound Module

Hi,

Is it possible to silence the TomTom Runner (1st gen) Smartwatch, so the sound module never ever peeps again, and there's only vibration? There's no need to make it reverse, for any reason. So one way, the hard way. :-)

Any hints, which one ist the sound module, I have to kill?

BTW: This question is dead serious, no joke! The clock - for me - is quite useless if I can't silence it, especially for alarms.
