Some outlet boxes (plastic) don’t require a stud for mounting as they have tabs that will rotate outward to retain said box against the backside of whatever wall material is being utilized. Hope this helps.
I know very little about it, but I was sure someone here would know. Thank you!

It’s called a ‘New Work Box’ and, as you write, the tabs rotate and clamp onto the back of the drywall via a screw.
Our house is made of SIP panels (structural insulated foam) and all of the exterior electrical boxes HAD to be new work boxes...
I was the ‘Sparkie’ on our home when we built it 30 years ago...
