Disable paste function that creates a file in Document libraries

[John Seto]

Is there a way to disable the ability to paste content into document libraries. When you paste in a document library a file is automatically created with the contents of what is currently in memory. This also works for images.

Strange thing is i can't find anything online to mentioning this functionality apart from this Japanese blog post

@John Seto you can use Azure AD Conditional Access to limit what people can do in document libraries from various devices, locations and applications. 

you can also use Azure Information Protection/Unified Labels to prevent copy/past from files, but the files have to be labeled in advance, so this would not apply directly to this scenario.
