It's better to change the needed keymap (i.e., view-mode-map) directly:

    (add-hook 'view-mode-hook #'my-view-mode-hook)

    (defun my-view-mode-hook ()
      (define-key view-mode-map (kbd "C-x C-q")
        #'(lambda ()
            (interactive)
            (message "C-x C-q is disabled")
            (ding))))
