Is it possible to remove the version number from the wp-login.php page?

Question

I am trying to hide all version number on my WordPress site. Is it possible to remove the ver= version number from the stylesheet link in the wp-login.php page?

href='https://example.com/wp-admin/load-styles.php?c=0&dir=ltr&load%5B%5D=dashicons,buttons,forms,l10n,login&ver=4.9.8'

I already have the following in my functions.php:

remove_action('wp_head', 'wp_generator');
add_filter('the_generator', '__return_empty_string');

function shapeSpace_remove_version_scripts_styles($src) {
    if (strpos($src, 'ver=')) {
        $src = remove_query_arg('ver', $src);
    }
    return $src;
}
add_filter('style_loader_src', 'shapeSpace_remove_version_scripts_styles', 9999);
add_filter('script_loader_src', 'shapeSpace_remove_version_scripts_styles', 9999);

Can someone please explain why this has been down voted so that I can improve the question? It shouldn't matter why I want to do it, asking whether something is possible is still a valid question.

The OWASP Application Security FAQ specifically recommends hiding version numbers and so it is a legitimate security step towards increasing the security of an application.

Of course, it's possible to remove the version number. Follow these steps:

1. Login to cPanel. Click on File Manager icon.
2. Choose document root or the public_html directory.
3. Open wp-content folder.
4. Click on the themes folder. Then open your active WordPress theme folder.
5. Scroll down to find functions.php file. Right-click and select Edit.

6. Add the following codes in functions.php file:

   functionwp_remove_version() {
   return'';
   }
   add_filter('the_generator', 'wp_remove_version');
   

7. Finally, click on the Save Changes button from the top-right corner.

Now, you will find that the WordPress version number has been removed from the stylesheet link. You can find more information about these steps right here.
