Hello,
Unfortunately, there is no way to restart the Wizard. However, you can manually configure DNS, timezone and NTP server from the admin shell CLI. The link I have provided below will show you how to gain CLI access.
configure CSPC via CLI
When you log into admin shell, you can run the following commands to configure DNS, timezone and NTP server.
admin# conf dns -a 192.168.1.1 192.168.2.1 :- To add the dns nameserver IP
admin# conf dns -d 192.168.1.1 192.168.2.1 :- To delete the dns nameserver IP
#timezone
#timesync
Thanks,
Taylor
