Hello @Nagraj ,
As is the case with every other Jet-based widget, it is possible to fully customize the FM widget according to the required specifications.
In File Manager, the uploading is handled by the separate service - fileManager.services.Upload. To be able to add FormData, you would need to override this service, for example: Code Snippet
