VR Pico4: Not finding a way to reduce aliasing

Godot Version

Question

I am geting upset with result in PICO4 when the question is reducing aliasing. It seems PICO4 lacks support to Foward+ and Mobile and compatibility does not seem to have much to help. I tried MSAA, but result is still very poor.

Anyone faced same issue?
