The difference between a pandemic and an endemic is that we don't want to stop an endemic. The virus is the same; the effects are the same but more averaged out with fewer peaks and troughs; they are just as bad.
In my opinion, there's no significant levers left to push to affect infection rates much.
Of course, we should be doing everything reasonable we can to tamp down COVID (and the flu). But short of permanent quarantine or forcing anti-vaxxers to get vaccinated, I'm not sure what there's left to do.
(It would be nice if we could socially normalize and encourage wearing a mask when one feels slightly sick, too).
