我试图将云母背景添加到我的应用程序中，我的应用程序中有页面，我怎样才能不将背景应用到它们上

应用程序.xaml.cs

        public App()
        {
            this.InitializeComponent();
            Host = Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder()
                 .ConfigureServices((context, services) =>
                 {
                     services.AddTransient<ShellPage>();
                 })
                 .Build();
        }
        protected override void OnLaunched(Microsoft.UI.Xaml.LaunchActivatedEventArgs args)
        {
            m_window = new MainWindow();
            m_window.Content = Host.Services.GetRequiredService<ShellPage>();
            m_window.Activate();
        }

        private Window? m_window;
    }

主窗口.xaml.cs

        public MainWindow()
        {
            this.ExtendsContentIntoTitleBar = true;
            this.InitializeComponent();
            TrySetMicaBackdrop(false);
        }

        private MicaController micaController;
        private MicaBackdrop configuration;

        bool TrySetMicaBackdrop(bool useMicaAlt)
        {
            if (Microsoft.UI.Composition.SystemBackdrops.MicaController.IsSupported())
            {
                Microsoft.UI.Xaml.Media.MicaBackdrop micaBackdrop = new Microsoft.UI.Xaml.Media.MicaBackdrop();
                micaBackdrop.Kind = useMicaAlt ? Microsoft.UI.Composition.SystemBackdrops.MicaKind.BaseAlt : Microsoft.UI.Composition.SystemBackdrops.MicaKind.Base;
                this.SystemBackdrop = micaBackdrop;

                return true;
            }

            return false;
        }

我应该为页面背景做什么
