Hide hard disk source

Hi guys!

I'm Paul from Novara, Italy!
I've try to search my answerin the web and into this forum, but I can't find it
I'd like to ask if exist a way to hide a hard disk source from video/music/film ecc...
My pc has got 2 hdd and I run LibreElec fron usb stick (full install on it)
I'd like for a specific user only have access to specific directory (not entire disk) and add t to source
So into drive I can save many folders but the user see only the one chosen by me (as a master uset of course!)

Thanks to everyone
