Hi,

On Chip Pearson's web site, there is an example of the removal of the procedure, "DeleteThisProc":

[ http://www.cpearson.com/excel/vbe.aspx ]

Deleting A Procedure From A Module

This code will delete the procedure DeleteThisProc from the Module1. You must specify the procedure type in order to differentiate between Property Get, Property Let, and Property Set procedure, all of which have the same name.

    Sub DeleteProcedureFromModule()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent
        Dim CodeMod As VBIDE.CodeModule
        Dim StartLine As Long
        Dim NumLines As Long
        Dim ProcName As String
        
        Set VBProj = ActiveWorkbook.VBProject
        Set VBComp = VBProj.VBComponents("Module1")
        Set CodeMod = VBComp.CodeModule
    
        ProcName = "DeleteThisProc"
        With CodeMod
            StartLine = .ProcStartLine(ProcName, vbext_pk_Proc)
            NumLines = .ProcCountLines(ProcName, vbext_pk_Proc)
            .DeleteLines StartLine:=StartLine, Count:=NumLines
        End With
    End Sub

It is possible. You need to use the Microsoft Visual Basic for Application Extensibility library, Set a reference to the library if you want to use early binding.
You will also need to give security permission: Trust Centre>Macro settings> Trust access to the VBA project model.

This Macro uses early binding
Sub DelProc()
    Dim vbp As VBProject
    Dim vbComp As VBComponent
    Dim code As CodeModule
    Dim strModuleName As String
    
    Dim strProcName As String
    Dim lLineStart As Long
    Dim lLineCount As Long
    
    strModuleName = "Module2"
    strProcName = "MyProc"
    
    Set vbp = ActiveWorkbook.VBProject
    Set vbComp = vbp.VBComponents(strModuleName)
    Set code = vbComp.CodeModule
    With code
        lLineStart = .ProcStartLine(strProcName, vbext_pk_Proc)
        lLineCount = .ProcCountLines(strProcName, vbext_pk_Proc)
        .DeleteLines lLineStart, lLineCount
    End With
End Sub
