Turn off "battery full" notification on Samsung Note 9 with android 10

Factual Questions
1

I have a Samsung Note 9 running android 10. Whenever the charging reaches 100%, the locked phone will beep and light up, showing the lock screen. It stays lit, and occasionally beeps until I unplug the phone or unlock and relock it. If I don’t unplug it, it will eventually do it all over again when it gets back to 100%.

How do I disable this notification, without disabling or silencing all others? I’ve tried to google this, and every hit gives instructions that don’t match what I see in my preference menus.

Bumping this thread, at long last. A few weeks after I posted that, I managed to find some combination of settings that keeps it from beeping when full (and now I can’t remember exactly what I did now) but it still lights up and shows its lock screen for as long as I leave it plugged in, whenever the battery is full or even just nearing full.

Anybody have any ideas for what to try, maybe something from different Samsung models?
