If you had followed note 3's forums for one day, you would know that what you want is not possible even in 2020.
How can you root if you don't know what it is. Lol. Not attacking you, but saving you from losing your note 3.
And if you some how don't care any more about Knox then root with cf auto root. Development forums and instructions there too.
Have fun with your note 3.
