  Instead of using it to exclude, use it as a selector to include. So for those columns you wish to export, add a special class to the th elements '.export-col'.

  {
                  extend: 'pdfHtml5',
                  exportOptions: {
                      columns: ':visible(.export-col)'
                  }
   },
  

  --- or ---

  Add special class to columns not to be exported '.not-export-col'

  {
                  extend: 'pdfHtml5',
                  exportOptions: {
                      columns: ':visible(:not(.not-export-col))'
                  }
   },
