+## Disable All Fields
+You can disable bidirectional updates using the following code
+```
+// field_XXXXXXXX = the field key of the field
+// you want to disable bidirectional relationships for
+add_filter('acf/post2post/update_relationships/default', '__return_false');
+```
+When doing this the field exceptions filter works in reverse and you must use that filter to enable fields that you want bidirectionality for, like this
+
+```
+// field_XXXXXXXX = the field key of the field
+// you want to disable bidirectional relationships for
+add_filter('acf/post2post/update_relationships/key=field_XXXXXXXX', '__return_true');

 ## After update hooks
