Deactivate scene reflection on specific object

I have an object that is supposed to be dark but it reflect the cubemap hdri of the scene. How do I deactivate the cubemap from this object only?
Thanks

You can’t explicitly do that. You can however set roughness of this object’s material to 1.

Ok, that’s right, it’s dark enough we aren’t supposed to see that much roughness. Isn’t the role of reflection captor to adapt the reflection to what it is surrounded by?
