How to disable touch event in AR foundation (arkit)? - unity3d

Question

I'm not very good with Unity especially in AR, but I finally built my first AR game. However, there is one issue: when I place my game objects on the plane, I want them to be still and want them to move when I touch the display. Is there a way to disable the touch hit or whatever it is called?

[RequireComponent(typeof(ARRaycastManager))]
public class PlaceOnPlane : MonoBehaviour

[Tooltip("Instantiates this prefab on a plane at the touch location.")]
GameObject m_PlacedPrefab;
/// <summary>
/// The prefab to instantiate on touch.

public GameObject placedPrefab

get { return m_PlacedPrefab; }
set { m_PlacedPrefab = value; }
}
/// <summary>
/// The object instantiated as a result of a successful raycast
intersection with a plane.

public GameObject spawnedObject { get; private set; }
void Awake()
{
m_RaycastManager = GetComponent<ARRaycastManager>();
}
bool TryGetTouchPosition(out Vector2 touchPosition)
{
#if UNITY_EDITOR
if (Input.GetMouseButton(0))
{
var mousePosition = Input.mousePosition;
touchPosition = new Vector2(mousePosition.x, mousePosition.y);
return true;
}
else
if (Input.touchCount > 0)
{
touchPosition = Input.GetTouch(0).position;
return true;
}
#endif
touchPosition = default;
return false;
}
void Update()
{
if (!TryGetTouchPosition(out Vector2 touchPosition))
return;
if (m_RaycastManager.Raycast(touchPosition, s_Hits, TrackableType.PlaneWithinPolygon))
{
// Raycast hits are sorted by distance, so the first one
// will be the closest hit.
var hitPose = s_Hits[0].pose;
if (spawnedObject == null)
{
spawnedObject = Instantiate(m_PlacedPrefab,
hitPose.position, hitPose.rotation);
}
else
{
spawnedObject.transform.position = hitPose.position;
}
}
}
static List<ARRaycastHit> s_Hits = new List<ARRaycastHit>();
ARRaycastManager m_RaycastManager;
}

Depending on your comments, if you are placing the object with the button, all you need to do right now is to disable this script that you have attached here. The object should not be moving since what causes its movement is this code bit in Update:
spawnedObject.transform.position = hitPose.position;
You can either comment out this part or deactivate the script, both should work fine.
