Is it possible to disable an FN key shortcut?

As the title says I need My FN key to be unable to use I believe its the FN + Y shortcut. This is because i use TFGH Y is a key i use for abilities instead of standard WASD to have more access to keys should I need them in certain games. This has created an issue because I use Right tab to check scoreboard and thus 2 times now it has completely shut my PC off or put it in sleep mode and logged me out of whatever game I am playing. I moved my check scoreboard key but still I dont want to accidentally click it and have this happen again. As far as i have read in threads its not possible to change these keys but just want to make my own thread to know 100% as nobody has talked about the specific issue im dealing with. Love the keyboard but its kind of frustrating you cant just disable one FN combination i would never use anyway. If anyone has any insight id appreciate it
