2019 Honda Accord Dashboard Rattle/buzz

My 2019 Honda Accord LX, which I purchased 2 days prior, making a hideous rattling sound from somewhere within the dash. Sounds like a Geiger counter. I'm a former master mechanic, and gave a small effort to track down the apparently common issue, to no avail.
I've tried switching modes quickly, removing the rubber strut caps, and found a couple of loose ducts/panels which I secured.

Apparently there is a known issue with the heater box which Honda hasn't addressed.
I did find a post on a forum where a member found a Chinese Honda TSB which showed a repair which involves immobilizing a part of the heater box/duct with foam and tape. This repair apparently worked for him.

The car goes in to the dealer Thursday.
I'll try the above fix if the dealer doesn't fix it.

I do have say, the rattle on the 2019 accord is crazy with rattles, I'm an audiophile and love to listen to music and the huge down side on the accord is you can't really enjoy any music with the rattle going on the side doors or the rear panel. I have insulated and patched every contact, loose point and there is still something rattleting, speakers have been upgraded. Had to disconnect the stock 8" subwoofer since that was rattling because it couldn't handle the base I wanted. my 2000 honda civic lx rattles less and sounds tight punch for the lows and crisp mids/highs. Now I do have this same sound that you are having, one more rattle to mess around with lol. I might as well have a rattle snake as the passenger.

Sorry folks, I forgot about this video.
I did get a grainy picture of the area, but don't think I can post it. Basically, I could tap on the storage box and reproduce the sound. When I slipped my hand into the area behind it, I could put a little pressure on the metal box (attached just above the storage cubby) and stop the rattle. This is where I wedged the ball. The rattle has not returned.
I provided the info to the dealer at their request.

same issue here. Did someone get to fix it yet? I have replaced the heater box and also the dealers added a foam tape to it, but I still hear this annoying noise
