How to postpone the action of the command | Translate | for a few seconds in Update?

I’ve tried everything with | Invoke | it doesn’t work that way.Can you tell me something please !

 Vector3 vector3 ;
 public float x;

 void  Update ()
 {
    vector3.x = x;
    transform.Translate(vector3 * Time.deltaTime) ;
 }

I’m not sure how to want/need to call the action. Can you provide more context?

You can try with this:

  Vector3 vector3 ;
  public float x;

  private bool isInvoked;
  
  public void PostponeTranslate() // <- call this to apply translate after a specific delay
  {
    float timeToPostpone = 2f;// <- set here any time you need/want
    Invoke("SetIsInvoked", timeToPostpone);
  }

  void SetIsInvoked()
  {
    isInvoked = true;
  }

  void  Update ()
  {
     if (isInvoked)
     {
       vector3.x = x;
       transform.Translate(vector3 * Time.deltaTime) ;
     }
  }

It’s not clear what you are trying to achieve, but I find coroutines a very good way to handle postponing or delaying code / instructions.
