1. Method 1 (CSS)

   You can hide it for all non-admins via CSS:

   function hide_ping_track_wpse_103502() {
       if( get_post_type() === "post" ){
           if( ! current_user_can( 'manage_options' ) ){
               // only for non-admins
               echo "<style>.meta-options label[for=ping_status], #ping_status{display:none !important;} </style>";
           }
       }
   }
   add_action( 'admin_head-post.php', 'hide_ping_track_wpse_103502' );

   Method 2 (PHP)

   You can also remove the native discussion metabox and replace it with your own:

   add_action( 'admin_menu', 'remove_discussion_meta_box' );
   add_action( 'add_meta_boxes', 'add_custom_discussion_meta_box' );
   
   function remove_discussion_meta_box() {
       remove_meta_box('commentstatusdiv', 'post', 'normal');
   }
   
   function add_custom_discussion_meta_box() {
           add_meta_box(
               'custom_discussion',
               __( 'Custom Discussion' ),
               'custom_discussion_meta_box',
               'post'
           );
   }
   
   function custom_discussion_meta_box($post) {
   ?>
   <input name="advanced_view" type="hidden" value="1" />
   <p class="meta-options">
           <label for="comment_status" class="selectit">
               <input name="comment_status" type="checkbox" id="comment_status" 
                      value="open" <?php checked($post->comment_status, 'open'); ?> /> 
               <?php _e( 'Allow comments.' ) ?>
           </label>
   
            <input name="ping_status" type="hidden" id="ping_status" 
                       value="<?php echo $post->ping_status;?>" />
   
           <?php do_action('post_comment_status_meta_box-options', $post); ?>
   </p>
   <?php
   }
   

   where the ping_status form input field is hidden with the current value.
