How do I remove a child or children in structure variables without JS?

How do I...?
1

I’m making Tetris without JavaScript codes as possible as I can.
But I’m stuck in dynamically managing structure variable without JS.
Is it possible to remove a child or children without JS?
So after removing a child, the result of VariableChildCount must be different.
