Is there a way to do the opposite of halation

I’ve got da Vinci resolve 20, im working on a MacBook max with maxed out specs and whatnot.

Halation threshold can be set top down just from the highs of highs to the mids to everything. It’s a cool effect to apply sparingly and subtle-ly, it makes things a little brighter and you can increase the spread and then bring the highlights down again.

but how about the opposite? I know it’s mimicking a film thing that actually happens and the opposite wouldn’t happen, but is there any way to try this out? Like to make the low-end more diffuse?
