If the server distro you are using is expecting a MySQL / MariaDB server to be present, then no, S3DB would have nothing to do with it.
You'd login direct to the MySQL via the command line as the database root user, create your service user and set password and permissions, create the database, and then kill the command line. That might look like:
SQL:
GRANT USAGE ON *.* TO forgottenserver@localhost IDENTIFIED BY 'super_secure_password';
GRANT ALL PRIVILEGES ON forgottenserver.* TO forgottenserver@localhost;
CREATE DATABASE forgottenserver;
QUIT;
Then you'd import the schema file with a command something like this:
mysql --user
%serviceuser% -p
%serviceuserpassword% db_name <
script.sql...
