Deleting Texture but keep reflections

Hey (beginner here),

Just to understand my problem… I have to shine a car light (with ies) on a road, wall and other objects. Very easy to this point. But my big problem is that I am going to use AR-glasses. I am sitting on a chair and watch the simulated light “projected” on the real road. My plan is to rebuild the RL place in UE5 and make every block or surface transparent…

But here is my problem. Is it possible to achieve that a block (a road in my case) can be transparent BUT without deleting the reflections you see (keeping the roughness of the walls, damaged parts of the road, shadows of the asphalt and so on). The “Rendering the scene with reflections only” is not what I want.

Thank you very much!
