File sharing is showing drives even though they aren't shared
Recently replaced a Mac Mini running High Sierra with a new M1 Mac Mini running Big Sur.
Most settings moved across OK except file sharing. I set up shared folders on the new machine and they work. However, it's also showing ALL hard disk volumes (unshared) as shares. I really do not want to share those over the network.
How do I stop my hard disks from appearing as shares on the network?
Currently, Windows File sharing is off for all users and guest access is off.
