Need info for dent repair or cover up on 017 taco offroad

I rolled a rock last weekend, I think, and have an upcrush ding on the bottom of the passenger fore fender box. The dent is barely noticeable except that it pushed the entire box up on that side, maybe 1/4", not really noticeable in photos but the plastic trim is now out on the guard and the top edge of the bed box. And it is out of alignment along the entire fore bed union. Does it matter? Not really. It's one of those "but I know it's there" injuries.

First, what is the name of the panel that received the injury, so that I can google search this? Photo is attached.

Second, is the passenger box a bolt on? Can this be adjusted DIY or is this an autobody shop adjustment?

Last, any cover ups that can go on both sides? The stone guard is damaged, which is an annoying but easy repair (I replaced them on my now long gone Tundra--the worst part is getting the fender guards on and off correctly). I was thinking maybe epoxying the dent after plastic stone guard removal and then putting X liner, a steel cover, or perhaps carbon fiber over where the original stone guard stickers go. I work with carbon a bit (I build boats) but getting them to be perfect will be challenging on those vertical curves. Any opinion? Please don't say, "Just drive dude no one will know". I will make that choice if this takes more than a coupe of hours/$400 but at the moment my post is to explore options.

Quarter panel or box side. The entire side would have to be replaced or just live with it. Good on you for playing with your truck.
