I realized you can simply use `remove-hook' to remove your
addition to it :)

Clear the whole thing:

  (setq conf-space-mode-hook nil)

Make your addition do nothing: (useful)

  (setq conf-space-mode-hook-f #'ignore)

Remove your addition: (useful to do after you do it)

  (remove-hook 'conf-space-mode-hook #'conf-space-mode-hook-f)

Your addition can look like this for, for example, the
`conf-space-mode-hook'

  (defun conf-space-mode-hook-f ()
    ;; do stuff
    )

Then add it, this won't remove any stuff that's already there
or will appear in the future: (pretty safe)

  (add-hook 'conf-space-mode-hook #'conf-space-mode-hook-f)
