"Yubikey support" is a meaningless phrase, anyway.
Bitwarden supports 2FA with Yubico OTP - although there's a bug so it works only for QWERTY layouts. Or you can use Yubikey's static password feature for your master password, I guess.
There's also OpenPGP Card and PIV, which, to my knowledge, is not used/supported by any password manager software except for `pass` and some compatible implementations.
