How can I disable the "Turn of PC" shortcut on my keyboard?

Hello,
I like my Razer Gaming mice but I truly hate my keyboard.
I have the Huntsman Mini v2 and I want to disable the FN+Y Hypershift function because the game I play I use the right Alt and that FN key a lot and it happens that I press the FN key from fast typing that then turns of my PC while a WAR/Event/Fight is going on, losing my position and losing the whole war for the whole nation (ingame nation).

Making the Huntsman Mini v2 total piece of garbage ONLY because that FN+Y key. For some reason there isn't even an option to disable the FN+Y key. Awesome (not).
