Hide page source

no – if someone has a bit of html knowledge it is not possible to hide it.

What do you want to achieve with this ?

Enfold offers something “to better reflect your own branding” via filter LINK

/** All of the Styling options you set in the theme’s Styling options get saved to a file in your uploads folder called enfold.css.
If you have changed the theme name or something like that you may want to re-name this file to better reflect your own branding. You can use the following function to do just that: */

add_filter('avia_dyn_stylesheet_file_path', 'avia_change_filename');
function avia_change_filename($stylesheet){
return 'myfilename.css';
}

i would like to see a page which is online with it.
i guess there are a lot of security plugins – but nearly 90% goes to the category: snakeoil

Currently, it has come to refer to any product with questionable or unverifiable quality or benefit.

A lot of things can be done without the need of a plugin and with the benefit that it will not cost performance
f.e.
in htaccess file !
this is one standard which i have on all my wordpress installs
On those page which are very important to secure i do a htpasswd / serverside login. etc.

# Secure your wp-config
# Disallow access to important files
<FilesMatch "(^\.|wp-config\.php|xmlrpc\.php|(?<!robots)\.txt|(liesmich|readme)\.*)">
   Require all denied
</FilesMatch>

# secure htaccess-file
<files ~ "^.*\.([Hh][Tt][Aa])">
order allow,deny
deny from all
satisfy all
</files>

if you have no other chance to make it this way – try.
Most security experts, however, do not see any sense in such plugins; rather another security risk.
