Can I rotate a 3D object in ARCore without using ARFragment?

I am working on a simple Android app using Sceneform in which I have to rotate a 3D object when a user taps on it. I know I can do it in ArFragment, but I don't want to use Augmented Reality for this purpose. I am simply using Sceneform as a 3D viewer and the only interaction user needs is to tap the display in order to rotate the model. Is it possible in ARCore without using its Augmented Reality shenanigans?

Yes it is! You should use only the SceneView component in your layout instead of the <fragment... block and from this point, everything is the same as with ArFragment. About the rotation: You still can use the TransformableNode (https://developers.google.com/ar/reference/java/sceneform/reference/com/google/ar/sceneform/ux/TransformableNode) if you want, it's not tied to the ArFragment or you could implement a basic rotation on tap: 

node.setOnTapListener { hitTestResult, motionEvent ->
   node.localRotation = Quaternion.multiply(node.localRotation, Quaternion(Vector3.up(), 180f))
}

This would rotate your node by 180 degree.
