If you don't want users to change the pivot table, copy it, and paste it
as values in a different workbook.
Or, you can use worksheet protection (Tools>Protection>Protect Sheet),
and don't add a check mark to PivotTable Reports.
You can also use programming to disable part of the pivot table, as
described here:

Worksheet protection can be cracked though, and someone could use
programming to enable the pivot table, so those methods don't guarantee
that the pivot table is completely restricted.
