I have a backround that I got from
https://aquadecorbackgrounds.com
It is made of styrafoam and some sort or hard coating, I had to silicone it to my back pannel inorder for it to sit in place.
I would imagine you are going to have to do something similar.
The only alternitive I can think of is some sort of suction cup attachment, but with it being made of foam, it would still have the potential to break free and float.
