Installing to a MySQL database that requires SSL

I am attempting to install Drupal 9 to a fresh host using an AWS MySQL RDS instance for a database. The database is configured to require SSL. When attempting to install via the web GUI, I receive PDOException: SQLSTATE[HY000] [3159] Connections using insecure transport are prohibited while --require_secure_transport=ON, which indicates that Drupal is attempting to connect without using SSL and that is working as one would expect. I have added the database config, including the appropriate PDO options for SSL, to settings.php but this causes a number of "unmet dependencies" errors that I believe stem from Drupal thinking that the database is already installed. I can connect to the db from the host in both the MySQL CLI and PHP, so I know the connection can work. How can I get Drupal to send its database test connection using SSL (or more generally, any driver specific options?)

EDIT: Looks like after adding the creds to settings.php, it did create some tables. However, the installation won't complete due to the below error:
