How to limit access by guests

How do I hide my NAS drive from guests on my network? Is there a way to only allow my devices to access it? Unless I missed it, I didn’t see this in the manual. If appropriate please direct me to a post if already in the system.

You do this via aguest account on a router. You can either allow internet access only or access to internet and home network. It is easy via my Asus router.

People who give out their own password to others are not thinking of the consequences.Guest accounts have their own passwords you give them. Mine are sinple, such as “pizza” etc.
