I can't remove jquery from wordpress, what should I do?

Question

CMS

I can’t remove jquery from wordpress , I
use different methods, I remove the code from functions.php and the functions itself, but this is an experiment) I
insert the code
remove_action ('wp_enqueue_scripts', 'jquery_init');
or
if ( !is_admin() ) wp_deregister_script('jquery');
but jq either remains or is deleted but not all files and writes an error that it does not see the jquery function,
what else can be done?

Answer 1

I usually use the following: wp_deregister_script

wp_deregister_script('jquery');
  wp_register_script('jquery', get_template_directory_uri() .
    '/js/jquery-3.2.1.min.js');
  wp_enqueue_script('jquery');
