Centreon Automation - OnPrem 22.10

Hello, I have an automation for centreon install, which can do everything, but the first steps after the first startup. Which is an issue for me, I want it to be seamless.What I want to achieve is , I would like to rebuild centreon any time I want, load back the database and all the checks. What I want to skip basically is the “Welcome to Centreon” Setup page. If anyone played with this idea, I would like to hear some advice :)
