Enable Secure Boot on GA-Z170-HD3 CF motherboard

Can someone give me instructions on how to enable Secure Boot in the BIOS/UEFI for the GA-Z170-HD CF motherboard?
The photo below shows the Secure Boot State is disabled and I want it to be enabled.

Correct me if I'm wrong but the option may not be showing itself because you have CSM support enabled, I believe it has to be disabled for secure boot to be available.

Thank you @Orcvader You are correct CSM Support has to be disabled for Secure Boot options to show I did not know this
