can't disable SSL certificate verification in dbconfig-mysql setup of PhpMyAdmin

I am attempting to set up a little PhpMyAdmin host in a LXC container running Devuan 6 (based on Debian 13) and I am running into problems with the setup script run by apt install, which I believe is actually dbconfig-mysql making its own set of debconf style prompts.

This is for my homelab, and my MariaDB server has self-signed SSL certs. The problem is that I can't figure out either of the following:

• how to have the dbconfig-mysql setup procedure not verify SSL certs
• how to manually run the portion of the procedure which sets up a database for PhpMyAdmin in order to completely work around the dbconfig-mysql setup process

Regarding the former issue, in /etc/mysql/mariadb.conf.d/50-client.cnf I set

        [client]
    ssl-verify-server-cert = off


  

and

        [client-mariadb]
    disable-ssl-verify-server-cert


  

but this doesn't affect the setup or dpkg-reconfigure process for PhpMyAdmin.

Regarding the second issue, I'm just stumped.

Any hints would be appreciated!

edit: changed dbconfig-common to dbconfig-mysql
