Disable ARKit image tracking

There are lots of tips on disabling plane tracking, but I can’t seem to find anything that shows how to disable image tracking in ARKit? Essentially I have images I want to ‘scan’ rather than spawn objects on.

Using this link, I figured it out! I added the following to GenerateImageAnchor.cs

UnityARSessionNativeInterface m_session;

	void Start () 
    {
        m_session = UnityARSessionNativeInterface.GetARSessionNativeInterface();
	}

void AddImageAnchor(ARImageAnchor arImageAnchor)
	{
            //at the bottom of this function
            StartCoroutine(RemoveAnchorCoroutine(arImageAnchor));
		
	}

   IEnumerator RemoveAnchorCoroutine(ARImageAnchor anchor)
    {
        yield return new WaitForSeconds(3.0f);
       //doesn't have to be in a coroutine, but for my uses it is
        m_session.RemoveUserAnchor(anchor.identifier);
    }
