(Help) G11CD BIOS modding

I’m planning to mod my H110l from a G11CD prebuilt system to show all the available options to me.
Tho it’s my first steps in the BIOS modding world, i would like to know if someone is able to guide me in this process?
I saw that a first attempt was made here but i don’t know if it was a success.
Thanks a lot for your help!
