I have a SharePoint farm with multiple content DBS, but I will shutdown database server because we need to use a different one.

I realized the people who installed this didn't use SQL alias.

I know how to make the backup and restore in SQL, and I know how to identify all SharePoint databases.

But how can I tell SharePoint (I guess with PowerShell), to change the database server name for ALL databases including Farm Config, central admin DB, etc.

You cannot change the SQL server name used by SharePoint for the Configuration database (and probably it's not that easy for all other DB).
So, the simplest solution is to create an alias now for the old server name!
I mean:
Let's say your old SQL is 'A' and you want to move all DBs to 'B': after restoring all DBs on B, create an alias on all SharePoint servers (with tool "cliconfg.exe") to make name 'A' point to 'B'.
