On a public forum I think it is just plain irresponsible to advise anyone to do anything other than follow safety rules and best practices including leaving safety devices functional. Collectively we have no idea of who or how old someone is that is reading this forum. Err if you must but do so at your own risk and without this members' (and I suspect the vast majority of this forum's membership) blessing.
You know another approach might be to replace the offending buzzer with an audio device more suited to the individual owner(s) liking. There are many types of whistles/buzzers/bells etc. that are DC 12v-48v capable and produce many different types of audio output. Heck, get one that plays a tune if you must, but as this thread and countless others before it demonstrate, don't just disable it.
Oh, and before it's brought up.....those around your cart can't hear an indicator light on the dash!
