If I understand the question correctly, you want to be able to patch a node without using the provided render/patch function, probably using something like `this.setState` inside a component like React.
No, this is not possible. The best way to use superfine is with a single view function that takes the state and returns your application DOM tree.
Of course, you can break up your app into smaller views and even memoize those based in a fragment of the state, but that's outside the scope of what Superfine provides out of the box.
