Azure WordPress deny access to xmlrpc

I am trying to disable xmlrpc.php by using a plugin and also by using .htaccess. But it doesn't seem to be working, when I hit example.com/xmlrpc.php I still get the following:

XML-RPC server accepts POST requests only.

I'm trying this in .htaccess file:

# Block WordPress xmlrpc.php requests
Files xmlrpc.php
order deny,allow
deny from all
allow from xxx.xxx.xxx.xxx
/Files

# BEGIN DS-XML-RPC-API
# The directives (lines) between BEGIN DS-XML-RPC-API and END DS-XML-RPC-API are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.

# END DS-XML-RPC-API
