Hey Everyone! Can you people help me on how to apply VR on a specific scene?

I want to make a main menu for game just like other games which includes buttons that will lead me to the next scene. I want my main menu to look exactly like that and when the game starts it gets converted into VR enviroment. P.S : Sorry my question is long but i am a beginner.

Here, put this on a GameObject in each scene and check or uncheck the checkbox in the inspector to have or not have VR in each scene:

using UnityEngine;
using UnityEngine.VR;

public class VRMode : MonoBehaviour
{
  public bool enableVR;

  void Start()
  {
    VRSettings.enabled = enableVR;
  }
}
