>>If you can't delete/remove the cert because you need it until it expires, that's an edge case I haven't previously encountered. I don't know how you might disable those warnings. And really you don't want to disable all warnings, just those for the one cert.

Over the years I've encountered many cases of spurious or unwanted Windows Event Log messages that simply cannot be disabled or fixed; MS itself has acknowledged many of them ("will be fixed in an upcoming version of Windows" but are never fixed for your current version).

If you're developing an Event Log monitor or dashboard you will need to have some way to store events that are known/confirmed to be spurious and which can therefore be ignored by your system. If and when you do that you can add these warnings about that particular cert to that database.
