Turn off startup sound

We constantly have power outages and split second power blips and everytime we do, the hardwired doorbell restarts and makes the god awful and horrendous startup sound. I need to be able to turn this off because we get some of these “brown outs” through the late evening and early morning and this is upsetting the neighbours by waking them up. This should have been something that was considered at inception of this product. Please make this a priority.
