Corsair's terrible iCUE software doesn't allow binding the G-Keys to F13-F18 unless iCUE is running. Here's how to get around that.
To assign Corsair K95 G1-G6 keys to F13-F18 you will only need iCUE to initially program the keyboard.
After the keyboard keys are assigned/programmed, you can uninstall iCUE and all the crap it comes with.

Using iCUE, assign G1-G6 to the following "Lang Keys" as pictured below.

• G1 = Intl`1
• G2 = Intl`2 (Katakana / Hiragana)
• G3 = Intl`3 (Yen)
• G4 = Intl`4 (Henkan)
• G5 = Intl`5 (Muhenkan)
• G6 = None-US \ and |

NOTE:
I used SharpKeys to figure out the actual scancodes (if you wanna use different keys, see: https://github.com/randyrants/sharpkeys). Most of the Lang Keys generate no scancode or actually do something, so only the ones I've chosen & like 2 others actually work.
Then looked into its source code to figure out how it works.
Finally I distilled only what I need to the above registry file.

Once the keys are programmed into the keyboard:

• Save K95 Keyboard F13-F18 Scancode Map.reg file anywhere and run it.
• Since we modified a SYSTEM key, you'll need to Reboot the PC.
  • May as well uninstall iCUE now as it'll ask to reboot after uninstalling.
  • Alternatively, disable iCUE from starting up & use System Informer to easily disable the services (in case you need iCUE again in the future)
    
• You will now have working F13-F18 keys corresponding to G1-G6.
