Might be something you have to experiment with. I personally would start by removing the panel and using an epoxy adhesive on the backside of the panel so that it’s reinforced on the back side. Or invest in a plastic welding kit. They’re metal tabs that are melted into the plastic to hold/ fuzeing the 2 sides together. Then the repair you do on the front side is purely cosmetic
You know, there are bunch of vinyl/plastic/leather repair places around that fix stuff like that. I've had other trucks that had holes drilled in the lower dash and they repaired so you would never know it was even there. It's also usually fairly cheap. Do a search in your area for one of those shops.
