I have the regular i5-6600 in my game system and it does have it so I am almost certain that chip does as well (and a quick search shows up someone with the k version who was able to enable it). For some reason the setting is under "peripherals" for me, I guess most likely the setting is hidden somewhere for you as well.

It looks like for CPU/firmware TPMs, not all motherboard manufacturers supported it on their 100/200-series models.
