No, you don't need to peel it off the back plate.

Don't remove it, because it's a key feature of the AM4 mount bracket. I'm unsure what its purpose is—possibly to balance pressure or stop shorts—but don't take it off. Also, it won't adhere to anything.
It's merely a plastic component to avoid short circuits in the metal backplate of the board. The insulation is straightforward. Keep it in place.
It is positioned behind the motherboard. If the plate is constructed from metal, it might be intended to avoid any short circuits. Previously, I used a plastic backplate with two rectangular foam sections secured by adhesive tape, which kept it firmly attached. However, this method seems different and doesn't seem to adhere properly. It appears smooth and wouldn't bond well with the motherboard.
I haven’t taken off the protective layer from my GPU, so in my view, you shouldn’t either. I’ve never seen an AM4 backplate that seems out of place—it’s definitely there for a purpose.
