Thanks Denis! No worries, I’ll try that

They left a note that in case the plugin was updated to apply this filter:
$this->options['customerID'] = apply_filters('get_eway_customer_id', $this->options['customerID']);

Line added to \wp-content\plugins\gravityforms-eway\includes\class.GFEwayPlugin.php in protected function getEwayCredentials()

add_filter('get_eway_customer_id', 'return_eway_id', 5, 1);
function return_eway_id($x){
	$post_id = $_GET['post_id'];
	$eway_account_no = get_field('eway_account_number', $post_id);
	return $eway_account_no;
}
