Filter custom data !

Hi,
I use this code to create a form data in my product :

add_action('wc_cpdf_init', 'prefix_custom_product_data', 10, 0);
if(!function_exists('prefix_custom_product_data')) :

   function prefix_custom_product_data(){

     $custom_product_data_fields = array();

..........

Can i filter this data with woof ?
