How to disable the textchanged event in the load event in Visual Studio C#?

Question

I have the following problem: I have a function that is called when the button triggers the textchanged event only when I start the program for the first time it calls the textchanged function in the load event. I want that when starting the program the textchanged is not triggered although the text of the label.Code of form_load:

private void Form1_Load(object sender, EventArgs e)
    {
        lbl_off.Text = "- Modo Offline, conecte para iniciar a contagem.";
     }

Event code text_changed:

  if (lb_TA.Text == "1")
            {
                turno_para_oee = "3";
                Tubeteira_Oee();
              }

  if (lb_TA.Text == "2")
            {
                turno_para_oee = "1";
                Tubeteira_Oee();
              }

  if (lb_TA.Text == "3")
            {
                turno_para_oee = "2";
                Tubeteira_Oee();
              }

}

There are two ways you can solve at first.

The first, and simplest, is to set this text in the Textbox on the screen itself, in the component’s text property, not needing to do this in the Load event.

The second way is to remove the Textchanged event setting from the textbox, and only set that event after you have changed the text, in the Load event:

private void Form1_Load(object sender, EventArgs e)
    {
        lbl_off.Text = "- Modo Offline, conecte para iniciar a contagem.";

        lbl_off.TextChanged += _aqui_seu_evento_onChanged_;
    }
