Problem with grainy LBSh pass

[Malaco]

Hey guys, do we have a fix or turn around for this? All my LBSh passes get noisy in render.
When I send it to post and try to denoise it also dont work.
Trying to increase info passess doesn't do anything.
I'm wondering how you guys handle this in your comps. Thanks in advance
I'm using V4.05

Bumping this because it's a recurring problem and I never figured out how to ideally deal with it
