Tactile in EU that is hard to depress?

There is a post by someone who is a heavy typist and keeps accidentally actuating switches.

That person is looking for a switch that is very resistant at the top, so that accidental keypresses are unlikely.

People have recommended Zealio V2, U4T, Gateron Kangaroo Ink, Holy Bobas, Haimu WS Heavy Tactile, and Harimau.

Of those, it seems Zealio V2, U4T, and WS Heavy Tactile are more likely available in EU.

Is there an aftermarket spring weight that would enhance tactility / resistance at the top?

​

Also, is there some kind of frankenswitch that is wildly difficult to accidentally press?
