No, most multisig wallets these days use p2wsh, so your receive address looks like every other address, but when you spend you reveal the whole script: it's a multisig with this many keys and this kind of quorum.

Taproot addresses let you hide some of this info: you can make it look like the keys you use to spend are the only keys in the multisig.

But my understanding of FROST is that the spending signature looks like a single key signing (even if it's a 2 of 3 or whatever).
