Spotlight's shaft created by HDRP volumetric fog flicker

Question

I am using HDRP volumetric fog to create light shaft for spot light I saw the light shaft flickering in game view, it doesn't happen in scene view. It shows a lot of flickering, the flickering is more obvious with light cookie and high intensity light setting Is there a way I can remove the flickering or at least slow it down?

I still don't find the solution. A quick fix is to reduce inner spot angle down. But I'm looking for a more permanent solution.

I'm a bit late but I figured out a fix for the same problem that happened to me (although mine didn't look as extreme as that). If you're using quite a recent version of unity's HDRP (At the time of writing, 7.3.1 is the latest version), make sure your spotlight doesn't have its angle higher than 170 (roughly), as this for me caused the flickering effect to go away. Additionally, in your fog volume component, there is a setting icon in the top right-hand corner. Click that and a few more settings should appear. You want to click the button labelled "filter". That should attempt to smooth out the fog, which again, helped in my case a little.
