Emissive material boost for lumen

Hey everyone,
I wanted to have really bright windows by setting the power of emissive material to a high number (say 50) but that causes lumen to scatter light from it everywhere (especially on exponential height fog)!

While I can completely remove it by disabling “Dynamic indirect lighting” on that object, that’s not what I want, I just want to reduce the effect like “emissive boost” in lightmass settings.

Is there any setting that I’m missing?
