I have just come across the same issue. I can see that this question was answered here

It looks like there is no way of actually removing the close button but you can intercept it and then ignore the event.

In the interest of completeness, this is the code you need to write:

private void CreateDockWorkspace()
{
    KryptonDockingWorkspace w = kryptonDockingManager.ManageWorkspace("Workspace", kryptonDockableWorkspace);
    kryptonDockingManager.ManageControl("Control", kryptonPanel, w);
    kryptonDockingManager.ManageFloating("Floating", this);

    kryptonDockingManager.AddToWorkspace("Workspace", new KryptonPage[] {
            NewPage("Overview"),
            NewPage("Main"),
            NewPage("Report"),
    });

    // This is where you wire up the CloseAction event handler
    var workspace = kryptonDockingManager.CellsWorkspace.FirstOrDefault();
    workspace.CloseAction += HandleTabCloseAction;
}

private void HandleTabCloseAction(object sender, CloseActionEventArgs e)
{
    // This event handler ignores the action
    e.Action = CloseButtonAction.None;
}

private KryptonPage NewPage(string name)
{
    var p = new KryptonPage();
    p.Text = name;
    p.TextTitle = name;
    p.TextDescription = name;

    content.Dock = DockStyle.Fill;
    p.Controls.Add(content);

    return p;
}
