Creating a pg_dump for specific tables

I want to exclude specific tables for backup, but backup.conf only accepts the list of databases that are assumed to be valid for the backup and dumps all tables in a DB. I'm wondering where I can modify pg_dump command

Start by locating backup.conf and the script or entry point that assembles and runs the pg_dump command. Read how database names are parsed and how dumps are invoked, then determine how specific tables should be represented in the configuration. Done means the requested tables can be excluded from a database backup and the relevant backup behavior is verified.
