Retrieving Billing Fields Setting When Localizing Script

I am trying to figure out how to set the localization of a script based on a billing field setting. The bt_field in the below code needs to be set to a field name that is chosen in the billing field settings. Can this be retrieved in the scripts method or via a custom method like I am attempting?

public function scripts() {
	$scripts = [];

	if( $settings = $this->get_plugin_settings() ) {
			[
				'handle'  => 'braintree_data_processing',
				'src'     => $this->get_base_url() . '/../assets/js/braintree-data-processing.js',
				'version' => $this->_version,
				'deps'    => ['jquery'],
				'strings' => [
					'bt_magic' => $settings['tokenization-key'],
					'bt_field' => $this->get_device_data_field_value()
				],
				'enqueue' => [
					[$this, 'aft_enabled']
				]
			],
		];
	}

	return array_merge(parent::scripts(), $scripts);
}
