Not that I know of, but Emacs always has functionality I donʼt know of
:-)

Iʼm in a terminal frame:

    (describe-key (kbd "C-;")) =>
    #("C-; is undefined" 0 3 (face help-key-binding font-lock-face 
help-key-binding))

which is exactly what you get in a GUI frame.

I think the best you can do is bind the key. If itʼs available, it will work.
