How to completely prohibit winbox from logging in with MAC address,

My friends, I want to ask in ROS 6.48

How to completely prohibit winbox from logging in with MAC address,

Don’t log in even if you know the MAC address of ROS

After I run the following script, I just can’t scan, but I can still log on.

/ip neighbor discovery set LAN discover=no

/tool mac-server set allowed-interface-list=none
/tool mac-server mac-winbox set allowed-interface-list=none
/tool mac-server ping set enabled=no

Thank you.
