Laptop with OpenServer. How to restrict access to internal folders on a local machine?

Question

open server

Good afternoon)
System - OpenServer is installed on the client's laptop (Win) and the site is available only for the local network.
Is it possible somehow by means of Windows or third-party programs to make the folder with the site inaccessible to the user of the Note itself, but at the same time for the site to work and OpenServer to function?
I understand that it is unlikely, but still, maybe there are ways)?
