Hi Rahul,
The reason why such a feature is not being implemented is because we don't have control over the number of files that the user selects from the file system and this is mainly because of security reasons.
What can be done is to manually check how many items are trying to be uploaded (on select event for example) and remove the files which exceed the max number with removeFileByUid method (or clear all selected files with clearFiles method).
Regards,
Martin
