Destructible - hide or destroy chunk when hit

I want to hide or destroy chunk when it hit by line trace immediately.(that means the chunk disappear before falling down)

I tried “Hide bone by name” bp node, it work for hiding mesh, but the collision still exist

How to fix it?

Or have other way to do it?

What’s the actual problem?

I updated the question.
And the actual problem is “How to hide or destroy chunk when hit immediately?”.
