[URP] Hwo to change Enviroment Lighting - Gradient source's axis?

Since I’m building a planet world, when I use Environment Lighting in Gradient Mode, the axis of the light should change in real time depending on the position of the player. I’m guessing it works in a similar way to Hemispheric Ambient Lighting using virtual spheres, so I thought it would be easy to change the axis, but I think Unity never wants user to customize it. If anyone has tried a similar method to mine and succeeded, please let me know how…

To make this work properly im fairly sure you need to write custom shaders and implement it yourself

Yes.. Maybe the only way is to modify the Environment Lighting related function directly within the URP Shader Library.
There is ambientProbe in the RenderSettings class, but when I look at the official document of the SphericalHarmonicsL2 structure, it seems that there is no direct adjustment to the axis.
