The first step is finding out what keymap to use.
In this case, it's `bookmark-bmenu-mode-map'.

This is the traditional way to remove a key binding:
bind the key to nil in the particular map.

(define-key bookmark-bmenu-mode-map "\M-o" nil)

(In recent Emacs versions there are also `unbind-key'
and `keymap-unset'.)
