I have found the touch screen interface bothers me a lot less when everything is silent. Our microwave is permanently muted. No beep on button presses, no beeping when it is done. Just blissful silence other than the humming of the mechanism itself.
My parents absolutely hate beeps so I often open up the appliance and look for the beeper on the circuit board and physically remove the beeper.
So far I've always been able to use side-cutters to cut the beeper leads because the beeper has been a through-hole device. I guess some modern PCBs you would need to desolder the beeper.
Obviously only if you don't have to worry about warrantee.
You also need to have a smidgen of technical ability to not cause other unforeseen problems.
I'm sure there will be YouTubes and articles on what to look for and what to do.
