I use a Panasonic NN-SD945S and it's configurable https://help.na.panasonic.com/wp-content/uploads/2023/02/NNS...

I leave it enabled though because it is not continuous and has like a TADA.WAV kind of vibe. So happy!

Oh, I have a Panasonic NN-GD38 that only beeps once. Sometimes I forget my food in the microwave because of it though. It's the best microwave I've ever had (also the first time I've ever spent so much on one).
