Wait time Before Camera Switching?

Is it possible to have a slight delay before camera switching with this script? Reason I ask is because some stuff does not play nice with certain public void functions. I think an IEnumerator might work here but fuzzy on how to code that?

 using UnityEngine;
 using System.Collections;
 
 public class CameraSwitcher : MonoBehaviour {
     public GameObject camera1;
     public GameObject camera2;
     public GameObject camera3;
     //public GameObject camera4;
     
     public void EnableCamera1() {
         camera1.SetActive(true);
         camera2.SetActive(false);
         camera3.SetActive(false);
         //camera4.SetActive(false);
     }
     public void EnableCamera2() {
         camera1.SetActive(false);
         camera2.SetActive(true);
         camera3.SetActive(false);
         //camera4.SetActive(false);
     }
     public void EnableCamera3() {
         camera1.SetActive(false);
         camera2.SetActive(false);
         camera3.SetActive(true);
         //camera4.SetActive(false);
     }
     /*public void EnableCamera4() {
         camera1.SetActive(false);
         camera2.SetActive(false);
         camera3.SetActive(false);
         camera4.SetActive(true);
     }*/
 }
