有没有办法在TabControl中禁用TabPage？

using System;
using System.Windows.Forms;

public class MainForm : Form
{
    private TabControl tabControl;
    private TabPage tabPage1;
    private TabPage tabPage2;
    private bool isTabPage2Enabled = false; // 控制 TabPage2 是否可用

    public MainForm()
    {
        tabControl = new TabControl();
        tabPage1 = new TabPage("Tab 1");
        tabPage2 = new TabPage("Tab 2");

        tabControl.TabPages.Add(tabPage1);
        tabControl.TabPages.Add(tabPage2);

        tabControl.Selecting += new TabControlCancelEventHandler(tabControl_Selecting);

        this.Controls.Add(tabControl);
    }

    private void tabControl_Selecting(object sender, TabControlCancelEventArgs e)
    {
        if (e.TabPage == tabPage2 && !isTabPage2Enabled)
        {
            e.Cancel = true; // 取消选择
        }
    }

    [STAThread]
    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new MainForm());
    }
}

using System;

        tabControl.TabPages.Add(tabPage2);

        Button toggleButton = new Button();
        toggleButton.Text = "Toggle Tab 2";
        toggleButton.Click += new EventHandler(toggleButton_Click);

        tabPage1.Controls.Add(toggleButton);
