This does not work, we found out the last time that the update downloads and installs a 4g modem to which there is no access yet.I tried to comment out lang sa software_upgrade.js ⇨ www/js/panel/router yung two function calls; getCpUpdateStatus() and GetSWVersionInfo()
The web interface you are changing belongs to the router, not the modem. You can change anything here, it will not affect the auto-update function.
Moreover, it does not work as you described.
