how to change the escape key double tap function ?

[Mu ah]

atm when i press the escape `⎋` key 2 times "double tap" it will print the last command from history, 

so is there a way to disable this or change it to do something else ?

Sure, but this is probably being done by your shell, not iTerm2.

If you're running zsh, this can be used to change it:

# Add this to ~/.zshrc
bindkey -s '\e\e' 'clear && echo "Double escape pressed!"'
