i want to disable the wifi button located above the F8 key because it keeps causing me to kill my hc d2 characters how can i disable it?

I believe you need to boot into the BIOS.

Press "F2" during the boot screen.
Look for the "Wireless" entry.
Press "Enter"
Look for something like "Wireless Control Hotkey".

It has been set as "WLAN&BT" by default, so switch it to "None", and it will disable the hotkey.

Hope this works!
