disable shortcut z + alt

[MrMaxime]

Hi,
I have an issue with some shortcut, I play a to a videogame, and I use frequently the keys "z" and "alt", but when I do this it (or more likely when a double tap on "alt") it's open me a menu like alt+tab but for icon shortcut is there a way to disable this shortcut or change the key binding ?

Thanks for your help.
