Need help exponential fog UE4 Oculus quest 2

Hi. I’m struggling to make work an exponential fog for a Oculus quest 2 game project. I followed what settings are needed to work and even put large amounts of values and nothing seems to work for it. Anyone that got experience with VR before or know of it that could give me any idea?

Anything besides ‘Disable vertex fogging in mobile shaders = false’?

Any change if you turn Mobile HDR on? (This is not a recommendation to use Mobile HDR with quest)
