Covert it into a Base Flange/Tab.
Unfold the part, selecting the fixe face and bends to unfold.

The model "looks" like a sheet metal part, and may even be made of sheet metal, but it bends in two directions at once, so the sheet metal tools won't handle it.
You could use the Surface Flatten tool to flatten it. I think this tool is only available with certain installations of SolidWorks though (i.e. Premium).
See if it is available in your installation.
