Feature Request URP shaders support for DrawMeshInstancedIndirect API

Hello Everyone,

I am creating my own hybrid rendering package based on DOTs + DrawMeshInstancedIndirect API.
I have a very basic knowledge about shaders and hlsl.

I am trying to:

1) create a hybrid renderer that generically overrides materials properties and supports Vulkan/ OpenGLES3.0+ (maximum 4 Compute buffers per stage). (DONE!)

2) make it support whatever is supported by the URP - SimpleLit Shader. (partially done)
* the problem i am facing now is, how can i apply overriden properties values ( like BakedLightmaps, LightProbes ..) that ive got from passed ComputeBuffers to the custom simpleLit shader ?

1) is there a workaround to do it ?
2) is Unity team planning to support DrawMeshInstancedIndirect API in URP shaders and ShaderGraph ?

Thanks!
