Remove Install.Lock Warning- Cloud Version

Hello,
I have been using dolibarr 12.0.3 hosted in AWS cloud (bitnami hosting). In order to remove the “Install.Lock” warning I have added “MAIN_REMOVE_INSTALL_WARNING Value 1” to other set up. Is it all right?

To add install.lick.php I can’t find the correct location in dolibarr cloud version. Please let me know it.

Thanks,
