Nope, not even close. Mainly just the ones with clicky (e.g. mx-blue, less so mx-brown) switches. It's an option but not a requirement, and honestly not that common for gaming-oriented ones, which typically have linear non-clicky switches, which can be quieter than membrane buttons, even. I like the semi-clicky brown ones for typing but haven't used them for years for noise reasons. My mechanical KBs have generally always had rubber o-rings that dampen the sound from bottoming out, too, a fairly common feature.

Apparently, based on your earlier post, you bought the noisy kind. That's on you.
