How can I exclude the BG from casting shadows into the apartment?

Hey everyone,

I have this scene (ss attached) and I would like the background to not cast any shadows inside the apartment (to not block the light coming in) but still get baked as static mesh, as it’s important for it to have proper lighting baked to it.

Is there a way to do that?

Here is a screen shot of it.

As you can see the trees are in the way of the sun and that considerably darkens the apartment.

Thanks all.

How about putting a spotlight in front of the trees shining into the apartment
