How to unbind TAB in normal mode?

[Óscar Fuentes]

I'll like to use Tab as per the Emacs bindings in normal mode, so tried
this:

  (setq evil-want-C-i-jump nil)
  (define-key evil-normal-state-map (kbd "TAB") nil)
  (define-key evil-normal-state-map [tab] nil)

No way. C-h k TAB in normal mode still shows:

TAB (translated from <tab>) runs the command evil-jump-forward, which
is an interactive Lisp function in `evil-commands.el'.

It is bound to TAB.

(evil-jump-forward &optional COUNT)


Any suggestions?
