9x6/7 foam in vents - alternate/best fix - this guy's on of us

This video popped up. It said it was a less invasive fix than the usual which involves pulling the head unit and cutting a hole in the HVAC plenum.

I've seen another fix that this fix includes which is getting to the hot/cold blend door from the frunk, but this one fixes the holes in both doors (hot/cold and floor/dash/windshield). It looks pretty easy. This guy may not be on the board, but he's clearly one of us in spirit. He 3d-printed plugs for the holes and used a borescope.

This seems like the best fix so far without paying some one a crap ton of money to remove the whole dash and replace the whole plenum.
