Hi for this particular case, launch.substitutions.TextSubstitution what you might be looking for.

You can see see example usage of the case here;

 joy_config = launch.substitutions.LaunchConfiguration('joy_config')
 joy_config_dec= launch.actions.DeclareLaunchArgument('joy_config', default_value='ps3'),

 final_string = os.path.join(joy_config, launch.substitutions.TextSubstitution(text='.config.yaml'))

The final string should be "ps3.config.yaml"

You can see complete example and refernce at here ; https://github.com/ros2/teleop_twist_joy/tree/foxy/config
