Hello,​

Is there any ShellHandler or TabBarHandler?

No. But you can create custom renderer like Xamarin.Forms for Shell (No need to add [assembly: ExportRenderer(typeof(Shell), typeof(MyShellRenderer))]). If you want to create a custom tabbar. Nomally, for android, you need to override CreateBottomNavViewAppearanceTracker. For iOS, you need to override CreateTabBarAppearanceTracker method.
https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/shell/customrenderers

Then, register your custom renderer for shell in the MauiProgram.cs.

   builder.UseMauiApp<App>()  
         .ConfigureFonts(fonts =>  
         {  
              ....  
         }).ConfigureMauiHandlers(handlers => {   
                
                           #if ANDROID  
                               handlers.AddHandler(typeof(Shell), typeof(CustomShellRenderer));  
                           #elif iOS  
                                handlers.AddHandler(typeof(Shell), typeof(MyiOSCustomShellRenderer));  
                    
                           #endif  
     
     
               });
