Hide the default About.txt file when creating a new folder

I'm using the azure asp.net core file provider and I understand why the default About.txt file is created when creating a new folder.  But I see in your documentation that I can set showHiddenItems to false (which it is by default) so I'd like to know how I can make that About.txt file a "hidden" file so my users won't see it.  Thanks!
