Since you said ASP.NET MVC and not ASP.NET Core, this icon will not display according to the documentation:

In Visual Studio 2022 version 17.2 and earlier, this feature was only supported for ASP.NET Core projects. In version 17.3 and later the projects targetting .NET support file nesting.

Your project(s) need to be targeting ASP.NET Core (or with more recent versions of Visual Studio, .NET as its called now).
