Any way to turn off the controller disconnect notifications only?

I would like to turn off the “controller not configured” notification that I get for my 4 Mayflash controllers every time retroarch starts. It’s easy enough to turn off all notifications, but it seems like this one should have a toggle just like all the others. There’s several (fast-forward, screenshot) that I would like to use but can’t because I’m then forced to see the controller disconnect notifications every time retroarch stars.

Is there any manual workaround to turn off the controller disconnect notifications only? If not, has a toggle been requested as a feature yet?
