Need help with finding any no sound or just really quiet keyboard to accommodate someone with Misophonia

So, in short, my girlfriend has Misophonia, and her trigger turns out to be the sound of keyboard switches.

Before she moved in with me, I had no idea, and now it's an issue which I want to accommodate somehow. As of right now, I am using California Access Goliath Black with orange switches, which are the "worst" according to her.

Occasionally, when I am not working and want to play, I use the Razer Huntsman Mini Analogue, and they are "mildly better"

I was thinking of maybe buying Rainy 75, both JWK WOB Switch and HMX Violet Switch, but it is hard to actually test them physically

As for O rings, I have them on my last keyboard with some random red switches, and they are also a "no-go"

I am still searching for either a new keyboard or just switches to replace, but still no luck, and so far from what I saw, I would have to import it to Europe, as there were no options close by

Have any of you been in a similar situation, or can you recommend something that I might have missed?
