Radiator brace - covered in styrofoam?

I am tinkering about putting a LED bar to my Roomster, and doing so in a hidden manner.

As the car is a facelift one, it has the honeycomb lower grille, and the idea was to mount it behind this - so under the front support beam.

Oddly, I found this to be covered with black styrofoam. Will it be doable in a simple manner to find room and fixations under there?
