How to deal with receive shadow property per renderer in SRP?

I am writing the custom SRP, and I met a problem.
The receive shadow property on the renderer is not affect in my SRP. I add a keyword to the command buffer to mark the shadow is on. And my object shader is check this keyword. But this way is not support the per-renderer receive shadow. How can I deal with the receive shader, which keyword should I check in the shader?

 

I also have this problem

 

I think the solution is use different materials, one for receive shadow other one not. Instead of using the renderer property.
