Keyboard clicks volume off - How?

This question has been asked before, but no one had a good answer. Hopefully someone does by now.

How do we turn off the keyboard clicks? And yes, it is part of the system setup. My son set up my new MacBook Pro, while I was driving home from the shop. And, as he went through the set up there was an option for keyboard clicks volume. I had no idea, so he set it to medium. I think it was in the initial accessibility setup, where one sets vision, hearing, and zoom and something else. But I can't find it in any settings, now that it is set up. I don't like loud. I usually work on my MacBook at night and like the quiet, when I'm working.

I've tried changing the alert volume, turning off user interface sounds, muting and dropping output volume. Nothing works. I type loud enough as it is, having learned on old manual upright typewriters, but this is louder than that.

I don't want to have to reset my MacBook. I have had too many issues with having to do that on my old one (that didn't have loud keyboard clicks).
