As far as I can tell there no such aircraft among the 10 7X registered in Switzerland...
And there can't be as X is usually reserved for helicopters. I suspect that Captainprop put the Xs in not say that it was Swiss registered without revealing all detail about it.

Second, Were you there when Dassault discussed this "request" with the EASA? I sorta doubt it. So I doubt you know what you're talking about.
Third, Does a manufacturer EVER tell the FAA/EAASA what to do? (or is it always the Feds telling them/us what to do?)
According to the EASA AD, that is what happened
To address this potential unsafe condition, Dassault Aviation has proposed to
EASA to prohibit, from the effective date of this AD, any flight operations of Falcon
7X aeroplanes, to which EASA agrees by issuing this AD.
