No. Virtual servers in Virtualmin are not independent virtual machines, they all share the same host services. A virtual server in Virtualmin is a user, a virtual host in Apache/nginx, one or more databases and database user, a virtual domain in Postfix, etc.

You cannot have both MariaDB and MySQL installed (easily) on the same system. And, you don’t need to. The two databases are functionally identical for most people and apps. Any differences are minor and easily accommodated with minor changes to code or schema.
