No, CentOS/Alma/Rocky only supports one minor release at a time (that's up to four major releases for a 10 year lifetime). You can stick to a major release but you have to update every 6 months or you'll skip the security updates too.
Red Hat supports 15-ish release streams at this time between RHEL7, RHEL8 and RHEL9. A lot of customers need that because validating a base system update takes months and they cannot afford not having security updates in the meanwhile.
The subtlety of different support levels for minor releases is something I hadn't come across before, thanks. I'm surprised RH haven't made more of that recently.
In fact the recent change basically consisted of going from 1 to 0 shipped stable branches (CentOS Stream is the mainline of RHEL). But most of those stable branches have never been public in the first place.
In my opinion 99% of end users would be served well by CentOS Stream, but the strong marketing of bug-for-bug compatible distros on part of Rocky (and to be honest it's a fig leaf to pretend CIQ is not behind that) hampered the adoption of CentOS Stream and the users' perception of its stability.
