Is it normal for DC trying o reach systems on 445 and 139
I get bruteforce alerts for only 1 system, even though DC is trying to reach almost every system in that zone on 445/smb

If you disable user identification on the public wifi zone you will lose User-ID visibility within that zone but that won't necessarily stop the agent from attempting to enumerate systems within that zone. You can either implement a security policy rule to deny/drop User-ID agent traffic to this zone or you could simply exempt the IP address for this system within the IP exemption list within the User-ID agent as seen here.
