Adding collision enabled to all the tiles in full_warehouse.usd in a more automatic way

Is there a way to add “collision enabled” to all the tiles in full_warehouse.usd in a more automatic way?
Currently, when my objects fall onto the floor, they go inside the ground despite having added colliders to my objects.

Is this necessary and is it possible I may not have added the colliders for my object correctly or regardless we need to have these colliders for the tiles too?

and

Is there a way to do this via scripting and save the USD?
