Do not want to add programmatically added contact in Experience Profile in Sitecore SXA

Question

We are adding contact through programming and it is added on Experience Profile after sometime.

How to avoid adding the same contact in Experience profile?

Code used for adding contact:

 using (var client = this.CreateClient())
            {
                    var source = "sitecore";
                    var id = email;
                    Tracker.Current.Session.IdentifyAs(source, id);
                    var trackerIdentifier = new IdentifiedContactReference(source, id);
                    var expandOptions = new ContactExpandOptions(CollectionModel.FacetKeys.PersonalInformation, CollectionModel.FacetKeys.EmailAddressList);
                    var contact = client.Get(trackerIdentifier, expandOptions);
                    SetEmail(email, contact, client);
                    client.Submit();

                    var manager = Factory.CreateObject("tracking/contactManager", true) as Sitecore.Analytics.Tracking.ContactManager;
                    manager.RemoveFromSession(Tracker.Current.Contact.ContactId); 
                    Tracker.Current.Session.Contact = manager.LoadContact(Tracker.Current.Contact.ContactId);
