Hi @ikako ika ,
Per my test, there is no such way to achieve your requirement by Jslink. The code will set all column to picture even if I don't set Templates. The result will be like following which other users will be blocked by red and the user's score also replaced by pic too.
As far as I know, there is no such function to hide cells. We can only hide the whole row by permission. You can refer to following steps.
Stop Inheriting Permissions first.
Add/remove groups/users as necessary
