Is there support for vertex index? uint vid : SV_VertexID

Is there support for vertex index? uint vid : SV_VertexID
On Standart pipeline with the exact same setup, I can batch up to 52 objects on the scene with 600 objects?
when switched to URP - it can no longer batch it with the exactly same shader but rewritten into URP supported one. Link to the repo : https://github.com/X-Crew/Morpeh.Baker/tree/develop/Runtime/AnimationBaker
it is free to use tool for changing skinned mesh animator/animations onto a simpler mesh with baked animation on it. It requires a lookup texture to look into the current position and the vertex id that will tell the right coordinate

Same problem here, someone can help with this?
