> There's no way in recent versions to disable them AFAIK. For a special case, it used to be possible to disable all notifications during set periods of time. Something like: Settings > Focus Mode > Set a Schedule > 4am to 3:59am Every Day. (So, during 1 minute of the day in the wee hours of the morning a notification could theoretically pop up, but in practice it never did.) Of course, this blanket approach only worked if one didn't actually want any notifications at all from any app (including OS upgrade nags, or anything else). But I used to compute that way. And it worked to prevent showing update notifications. No idea if it works on the latest macOS versions, but it did not not too many years ago. Of course, I do rely on notifications now, though...
