How can I delete the hdri reflection from a window glass?

[Riccardo.3D]

I set the hdri with coronabitmap and then I add it to the Environment Map in the Environment tab.
But I don't want to see the hdri reflection in the window glass. How can I do?

You can override environment reflections and/or refractions in the glass material. You can add there any other HDRI, or just plain solid colour.
