Instead of blocking what is a bad method, one should allow what is acceptable good method

add_header Allow "GET, POST, HEAD" always; 
if ( $request_method !~ ^(GET|POST|HEAD)$ ) { 
   return 405; 
}

You will have to add more methods to this if your app uses methods like PUT, PATCH, DELETE, OPTIONS

Or you can block the request using approach mentioned in below
