No worries all, I probably really confused it.

I just added a Text Field and added a CSS class of hidden-field and then just did this:

add_filter('acf/update_value/key=XXXXXXXXX', 'my_acf_update_value', 10, 4);

function my_acf_update_value( $value, $post_id, $field ) {

    if( !$value ) {
        return uniqid();
    } else {
        return $value;
    }

}
