Foliage Flickering/Jittering

I need help with foliage flickering issue in 5.6 that I cannot
get rid of. Tried everything that comes to my mind and everything I have seen on the internet. Nothing helps. It is happening with Nanite enabled and disabled, with VSM and normal shadows, with Lumen and without Lumen, with various material settings. Not sure where to look at anymore, it is project breaker for me. It seems it happening only on shadowed parts of the mesh but I m seeing it even if I disable shadows completely. Thank you!

r.Lumen.ScreenProbeGather.ScreenTraces.HZBTraversal=0 —this is working for everyone but not for me. Also tried every single engine.ini change but nothing helps.

One video of material is simple material for foliage I made just to test it, another one is Megascan, both have same issue.
