Disabling 'mail drop' in Mac Mail

New Contributor II

When setting up an account in Mail (Mail > Preferences > Accounts) on a Mac, there is a check box that allows you to 'Send large attachments with Mail Drop'. It is my understanding that this uses iCloud. It saves a copy of the file on iCloud and provides a temporary link to the recipient to allow them to download the file. Is there a way to disable the option for the user to check this box?
