How to add Snow to Terrain using Shader Graph?

Is there a way I could use shader graphs to add snow to terrains?

What I did:
I created a snow system watching youtube tutorials, I’ll mention it briefly below
Created ShaderGraph for snow
Create material using the shader graph
Created a Custom Pass Volume object
Added a DrawRenderersCustomPass to it
Assigned the created material in the overrides section

Result:
The above steps resulted in adding snow to all the objects in the scene but NOT the terrains

What I wish to do:
I would like to add snow to terrain dynamically so that I can reuse this system in other projects/terrains as well.

P.S.
I’m new to Unity and I’m still in the phase of figuring things out. Don’t know where to turn to, hence I’m asking here
