Hide "Add Note" option for users

Hide "Add Note" option for users

I want hide "add notes" from requesters. And I made changes according this KB: https://pitstop.manageengine.com/portal/kb/articles/hide-add-note-option-for-users
But in last SDP versions this doesn't work.
It there some way to accomplish in version 10500?
