My dishwasher is quiet, bit my washing machines and the dryer are talkative. Both have a setup AND a dedicated quiet mode button to silence them. Maybe you should invest some time to RTFM?
Now you mention it, I will. I literally had no clue it could/would/might have such a feature, its interface is very simple compared to the Bosch I had before, so I never even thought to look for an STFU mode.
