Wireshark doesn't provide any packet editing capabilities.
(Older versions of the Legacy (Gtk) Wireshark (such as 2.2.x) included a basic packet editor feature that you could enable at the bottom of the Edit -> Preferences page, which will allow you to edit packets by right-clicking on the packet details pane and choosing Edit packet, but that feature has since been removed.)
If you're on the Windows platform, then your best bet might be to try tools like TraceWrangler or WireEdit. If you're on another platform, then have a look at the Capture file anonymization section of the Wireshark wiki Tools page for a list of some other tools that could possibly help you.
