update links prompt issue - vba

Question

I have a length code which opens set of files, unhides and navigates to a particular worksheet, copies a range and pastes that range in another workbook.
The problem is whenever the code opens these files a popup message to update links appears. I understand it can be solved with updatelinks = 0 however wanted to know where should i include this in my code.
Also the code takes time to execute, so is there any modifications for faster execution.
Sub mergeallinputworkbooks()
Dim wkbDest As Workbook
Dim wksDest As Worksheet
Dim wkbSource As Workbook
Dim wksSource As Worksheet
Dim MyPath As String
Dim MyFile As String
Dim FolderName As String
Dim oCell As Range
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Application.EnableEvents = False
Set wkbDest = ThisWorkbook
Set wksDest = wkbDest.Worksheets("Master Data")
With Application.FileDialog(msoFileDialogFolderPicker)
.AllowMultiSelect = False
.Show
On Error Resume Next
FolderName = .SelectedItems(1)
Err.Clear
On Error GoTo 0
End With
MyPath = FolderName
If Right(MyPath, 1) <> "\" Then MyPath = MyPath & "\"
MyFile = Dir(MyPath & "*.xls")
Do While Len(MyFile) > 0
Set wkbSource = Workbooks.Open(MyPath & MyFile)
Set wksSource = wkbSource.Worksheets("Scoring DB")
ActiveWorkbook.Unprotect ("pyroo123")
Sheets("Scoring DB").Visible = True
Sheets("Scoring DB").Select
Range("A4:W4").Copy
Windows("Performance Dashboard.xlsm").Activate
With Sheets("Master Data").Range("$A:$A")
With Sheets("Master Data")
Set oCell = .Cells(.Rows.Count, 1).End(xlUp).Offset(1, 0)
End With
oCell.Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=False
Application.CutCopyMode = False
Windows("Performance Dashboard.xlsm").Activate
End With
wkbSource.Close savechanges:=False
MyFile = Dir
Loop
Application.ScreenUpdating = True
Application.DisplayAlerts = True
Application.EnableEvents = True
End Sub

For you links issue, have a look at this post. There should be enough information there to give you a good indication of how and where to use the link update.
Now code suggestion:
To improve performance of your code, I would suggest not to interact with worksheet where not necessary. Rather than 'Copy and Past' assign the range to an array:
arrMyRange = Worksheets("SourceWorksheet").Range("A4:W4")
This will create your array. Now assign the array to your location:
Worksheets("DestinationWorksheet").Range("A1").Resize(UBound(arrMyRange, 1), UBound(arrMyRange, 2)).Value = arrMyRange
A1 can be changed dynamically if required.
