You can create UEFI Shell application that would utilize EFI_HII_DATABASE_PROTOCOL.ExportPackageLists function to export all the package lists from the HII database. Iterate on PackageLists and save them as files, then try to use ifrextractor on each one. To make things more clever, you can peak inside each of the PackageLists and save only the ones that have FORMS package inside.
