If you really want to remove the scripts, after acf_form_head() you can dequeue the scripts https://codex.wordpress.org/Function_Reference/wp_dequeue_script and css https://codex.wordpress.org/Function_Reference/wp_dequeue_style. Please note that I do not know what effect this will have on the operation of your front end forms. Many scripts rely on other scripts and removing any one of the could cause your form to stop working.
