Fido2 and Fingerprint scan vs touch

I’m evaluating the new Yubikey Bio keys and there’s some issues I don’t quite understand regarding presense touch and actual finger print verification.
If I load the resident key (i.e. ssh-add -K), things seem to work as expected and the wrong finger print results in dropping down to another authentication method.
If I don’t use ssh-add -K, then it seems ssh only verifies presense. I basically want to enforce proper fingerprint recognition always. Is there a way to do this?
