How to block skylight in indoor environment?

Could you explain a bit more how to do that?

I have the same situation, I use skylight to have shadows and corners where no light is coming in (but outside, not interior) to be **not **pitch black and to control a minimum of light in the outside world . But there are also houses with bigger entrance, you can look inside and outside. No door, very big entrance. And that the skylight is shine inside the house/rooms is really annoying.
If this is a solution, would be nice to know how to block skylight using “volumetric lightmaps (probes)”.

If someone knows a easy way in 4.25/4.26 please let me know.
