Yes, however, those are not updaters, but full installers for those respective versions.
So, if you, for example, have Monterey 12.2 now, and want to go to 12.2.1 for some reason, software update won't show you the choice to update to 12.2.1 - but will show you the 12.3.1 update - nothing in between.
As in the past, you can download various combo updaters, and the "dot" updaters, up to Catalina 10.15.7, and security updates for Catalina, too.
But, nothing, no updaters for Big Sur and Monterey, just the full installers. The updates are available to install, but not as a separate download, and only until the next update is released.
I have become used to simply downloading each full installer as they are released (12GB or more downloads, several times a month adds up quickly!), make bootable installers, and use those when needed. Would be nice to just download the separate updates, but no more, I guess.
