How to disable animated model child mesh renderer?

I downloaded a model from the Asset Store, I have it animating, but after a certain point I want to stop rendering the model and play it's particle effect (an explosion).

The Skinned Mesh Renderer is a child of the parent GameObject.

How do I access that child skinned mesh at runtime to disable its renderer without disabling the particle effect.

If i simply use renderer.enabled = false, the model is still renderer but the particle effect doesn't render.
