Gigabyte GA-H110M-S2H : Disable in bios, Hyper Threading

[briketi]

Hi

My setup :

CPU : I5 6600k
Motherboard : Gigabyte GA-H110M-S2H
GPU : GTX 960
OS : Windows 10

After update my motherboard to F20 Version from this : http://www.gigabyte.fr/products/product-page.aspx?pid=5606#bios

I can't disable in bios : Hyper Threading...

How to downgrade bios, or disable the hyper threading for my CPU Intel i5 ?

Thank You

Hyper-Threading is a hardware feature that the i5-6600K Processor does not have.
