Change offset values of HDRP/Unlit shader

Hello,

I am fairly new to this and the HDRP in general so I apologize in advance if there is an obvious solution to this.
My goal is to create a scrolling background during runtime and usually, you would do this by altering the offset value of your material. How can I access and change these values in the HDRP/Unlit shader during runtime?

If I were to chose a normal Unlit shader for this, the texture becomes unclear due to the fog. Since I would like to keep the fog active, I would prefer not having to switch to the normal Unlit shader.

 

Nevermind, I've created a custom HDRP shader via shadergraph that manipulates these values quiet easily. Many ressources to be found on that too.
