How to create an extension method for the type of a class in VB.NET

I'm creating an MVC framework that will work similar to the Entity Framework inside a VB.NET project where I've created an attribute called TableAttribute that will set the table name and the schemas to the model , like this:

Namespace Models.DataAnnotations
  <AttributeUsage(AttributeTargets.Class)>
  Public Class TableAttribute : Inherits Attribute

    Sub New(Name As String)
      Me.Name = Name
    End Sub

    Public Property Name As String
    Public Property Schema As String = "dbo"

  End Class
End Namespace

So I can add it to my models that will serve to make the application data layer:

Imports Models.DataAnnotations
Namespace Models
  <Table("Usuario", Schema:="Sistema")>
  Public Class UsuarioModel
    Public Property Id As Integer
    Public Property Login As String
    Public Property Senha As String
  End Class
End Namespace

In addition, I have a Module that is related to Namespace.Models which holds a series of extension functions for the models:

Imports System.Reflection
Namespace Models
  Public Module ModelsExtensions
    <Extension()>
    Function GetTable(Obj as Object) as String

      Dim type As Type = Obj.GetType()
      Dim temp As TableAttribute = type.GetCustomAttributes(GetType(TableAttribute), True)(0)

      If (temp IsNot Nothing) Then Return $"{temp.Schema}.{temp.Name}"

      Return $"dbo.{type.Name}"

    End Function
  End Module
End Namespace

My problem is that, in order for me to get the name of any table, I am forced to instantiate it by making a new Usuario().GetTable() .

Is there any way I can extend a method directly to type Usuario ? The result I hope would look like this: Usuario.GetTable()
