Don’t know but give it a try…

It shouldn’t matter. Challenge Response is challenge Response… It’s documented on the nk webpage. I wrote about how to set it up on nk3 and a onlykey here: [Using Challenge-Response (HMACSHA1) with the same Secret on a Nitrokey 3 and on a Onlykey to unlock a KeepassXC Database](https://support.nitrokey.com/t/using-challenge-response-hmacsha1-with-the-same-secret-on-a-nitrokey-3-and-on-a-onlykey-to-unlock-a-keepassxc-database/5722) maybe it helps… Spoiler: the nk3 wants to have the secret base32 encoded.
