How to bind CTRL + Enter in zsh?

Question

I want to bind Ctrl+ Enter ↵in zsh:

bindkey '^M' autosuggest-execute

But it seems that the terminal sends the same escape sequence for any modifier key except Alt.

$ showkey -a

Press any keys - Ctrl-D will terminate this program

^M       13 0015 0x0d # Enter
^M       13 0015 0x0d # CTRL  + Enter
^M       13 0015 0x0d # SHIFT + Enter
^[^M     27 0033 0x1b # ALT   + Enter
         13 0015 0x0d

I am not sure what the problem is specific to gnome-terminal. I also tested this in mate-terminaland xterm, and the results were the same. Is there any way to detect CTRL + Enter?
