Sun Disc without atmospheric fog?

Wondering if it’s somehow possible to get the sun disc effect with light shafts without the atmospheric fog?
Basically my game is supposed to be mostly black and white and since there’s no option to change the color of the atmosphere, I was thinking maybe there’s a way to get the sun disc without it?

Sun disk is a spheremask in the sky sphere,you can even simulate the halo with another spheremask

I’m not so worried about re-creating the disc as much as the light shafts but thank you.
