Is there a way to reduce Draw Calls?

Hi Guys,
I used this tool Unity Asset Store - The Best Assets for Game Making which has reduce Draw calls from 1.5k to 90 but this is working just on static objects I have every Objects with rigidbody and collider.

Is there way to make something similar to objects with rigidbody?

You can use “Occlusion Culling” only those part will be render which are in-front of camera this will reduce your draw call
