You can do it in code behind on the Loaded event. Loaded="Ribbon_OnLoaded"

private void Ribbon_OnLoaded(object sender, RoutedEventArgs e)
    {
        int childControlCount = VisualTreeHelper.GetChildrenCount((System.Windows.Controls.Ribbon.Ribbon)sender);

        if (childControlCount != 0)
        {
            for (int i = 0;
                i < VisualTreeHelper.GetChildrenCount((System.Windows.Controls.Ribbon.Ribbon)sender);
                i++)
            {
                DependencyObject child = VisualTreeHelper.GetChild((System.Windows.Controls.Ribbon.Ribbon)sender, i);

                if (child is Grid)
                {
                    ((Grid)child).RowDefinitions[0].Height = new GridLength(0);
                }
            }
        }
    }

The content needs to be hosted inside a RibbonWindow instead.
