Refraction in shader graph using the Built-in render pipeline

I know that in the Scriptable render pipeline you must enable the "Opaque Texture" option for the "Screen Color" node to work, but in the Built-in render pipeline there's no such option and the Screen Color node return a gray color.
.
Is it possible to have the Screen Color node working or somehow access the Grab Pass in the shader graph while using the Built-in render pipeline?
the built-in particle shader has a distortion that just works perfectly, is it possible to somehow achieve that in the shader graph?
Thank you.
