Is MySQLd Port 3306 Being Open Vital to Virtualmin

Does Virtualmin / Webmin have any functional need for port 3306 to remain open. I do not use a separate database server and I don’t have any desktop mysql apps that need access. Would it be safe to close port 3306 without hurting my Virtualmin installation?

By default the port is closed in the firewall and mysql is only listening to localhost anyway.
So not much to close, except for actually disabling mysql all together.
