How to hide file extensions for all files, including overwriting the files individual setting?

Question

Client wants to hide file name extensions to avoid removing them by mistake when renaming files. I used Finder preferences to uncheck the "Show all filename extensions" option.

This only hid a extensions from some files. Most files in various locations still show the extension, including in newly downloaded files.

When right clicking on the files and going to "Show Info", I can see each file has this checked (including newly downloaded files).

Is there a way to force all files to not show the file extension?

We use a tool to drag and drop process files and remove that metadata.

Test it and then make a droplet if you continue to get specific files with setting you don’t like.
