Sentora is not designed to run in a subfolder. Some functions may not work properly. But, you can change the login port of the panel which should be more than enough to help 'hide' your panel login.
Either in Module Admin > Apache config or through phpMyAdmin as root, in the sentora.x_settings table, row 121 (sentora_port). Change it to whatever you want. Make sure the port is open in your firewall. Wait for the daemon to run (~5mins) for the changes to take affect.
