It depends upon how hyperlinks are added in the PDF document. Are they added using annotations or JavaScript actions? Would you kindly share a sample PDF document with us so that we can test the scenario in our environment and address it accordingly.

Below is the code snippet to extract the hyperlinks from your PDF:

Dim pdfDocument As New Document(dataDir & "Demo.pdf")
Dim pages As PageCollection = pdfDocument.Pages

For Each p As Page In pages
    For Each annot As Annotation In p.Annotations
        If annot.AnnotationType = AnnotationType.Link Then
            Dim a As LinkAnnotation = CType(annot, LinkAnnotation)
            Dim URL As String = String.Empty
            Dim dest As IAppointment = a.Destination

            If a.Action IsNot Nothing OrElse dest IsNot Nothing Then
                If a.Action IsNot Nothing Then
                    If TypeOf a.Action Is GoToURIAction Then
                        Console.WriteLine(DirectCast(a.Action, GoToURIAction).URI)
                    End If
                End If
            End If
        End If
    Next
Next

And in order to delete/remove the hyperlinks, you can simply remove the annotations from the PDF page:

Dim pdfDocument As New Document("input.pdf")

' Iterate through the pages
For Each page As Page In pdfDocument.Pages
    ' Remove hyperlinks from the page
    page.Annotations.Clear()
Next

pdfDocument.Save("output.pdf")

And another issue is that how to get the screen tip text of the hyperlink?

@ducaisoft

By screen tip, do you mean the tooltip or title of the hyperlink that appears while hovering the link?
