There are insufficient instructions and examples in

Info 49.3.6 Rebinding Keys in Your Init File

as of emacs-version "26.3"

to allow the user to get rid of e.g., (seen with C-h b)
C-,		flyspell-goto-next-error
C-.		flyspell-auto-correct-word
C-;		flyspell-auto-correct-previous-word
C-c $		flyspell-correct-word-before-point

Leaving only
C-M-i		flyspell-auto-correct-word

The user tries everything
(eval-after-load "flyspell-mode"
  '(add-hook
    'flyspell-mode-hook
    (lambda ()
      (setq flyspell-mode-map nil)
      ;;too close to C-/ (undo) and already on ESC TAB:
      ;;(define-key flyspell-mode-map [(control ?\.)] [])
      (define-key flyspell-mode-map (kbd "C-,") (lambda () (interactive))) #<---last time what I was told to try
      (define-key flyspell-mode-map (kbd "C-.") (lambda () (interactive)))
      (define-key flyspell-mode-map [(control ?\,)] (lambda () (interactive)))
      (define-key flyspell-mode-map [(control ?\.)] (lambda () (interactive)))
      (define-key flyspell-mode-map [(control ?\;)] (lambda () (interactive)))
      (global-unset-key [(control ?\,)])
      (global-unset-key [(control ?\.)])
      (global-unset-key [(control ?\;)])
      (setq flyspell-mode-map nil)
      )))
(global-unset-key [(control ?\,)])
(global-unset-key [(control ?\.)])
(global-unset-key [(control ?\;)])
(defvar flyspell-mode-map "")
(add-hook 'flyspell-mode-hook
	  (lambda ()
	    (define-key flyspell-mode-map (kbd "C-M-i")
                    'flyspell-auto-correct-word)))
(setq flyspell-mode-map nil)
(global-set-key (kbd "C-M-i") 'flyspell-auto-correct-word)

Alas nothing will give the user the aforementioned desired result.
Please put examples in
Info 49.3.6 Rebinding Keys in Your Init File
showing how to remove entire keymaps with one line,
and then how to sparsely populate them back. Thanks.

I think there's a limit to what we can say in the user manual that
describes Lisp facilities.  Users who are serious about key-binding
customizations should read the ELisp manual to augment and complement
what is in the user manual.

Fine. Keymaps can only be added to.

OK the answer is not in
(info "(eintr) Keymaps")
(info "(elisp) Creating Keymaps")
however possibly in
(info "(elisp) Changing Key Bindings")

I agree.  Since no one besides the OP has expressed a different
opinion within two weeks, I'm closing this bug now.

Actually 39802 solves the need for 39630 and 39631.

NP> I don't know about 39631

OK, I suppose to solve 39631 somebody could use the lisp equivalent of
for(all the keys present in a given keymap){use the method of 39802 to unbind it}

So maybe document that in some elisp manual or something, mentioning
that maybe there is no way to zap the whole keymap with one line of lisp(?).
