Is it redundant or useful to add a UFW rule to deny root when ssh already does?

I manage a Debian (Bookworm) host. The sshd config is set to disallow login as root. I've tested that one cannot login as root, as expected. However, I see hundreds of login attempts daily as root in /var/log/auth.log. Even though I have what I think is adequate reason to believe they can't succeed, the constant brute-force attacks make me uneasy. I am considering adding a ufw rule in /etc/ufw/before.rules to block any attempt to connect with ssh as root. Is there any value in adding the proposed rule or something like it? Or would that be redundant and/or potentially cause problems?
