Disable LightShaft Bloom of Transparent Materials

Hi there!

We’re working on a project where we need our DirectionalLight to cast light shafts bloom and have it NOT being affected by certain translucent material particles… like it is here. Notice the big yellow rays.
How can we achieve this?

On a side note, and our temporal solution; masked materials do not cast light shafts.

Edit: This is on a VR project with ForwardShading enabled.
