I wasn't trying to use it, I was just looking around and came across the "YubiKey Personalization Tool", which doesn't show anything about FIDO2.
Now that FIDO2 has been mentioned as something that solves this issue, it turns out there's another tool called the "YubiKey Manager", which allows you to configure/toggle various "applications" on a key, including Yubico OTP and FIDO2.
