In their ARK description, Intel admits that they support `vt-d` virtualization technology on i7-6700HQ Processor. But nowhere in Bios (version E5CN56WW), it has mentioned on how to enable it. The only related configuration seems to be named Virtualization which is enabled, but I can't confirm it by enabling IOMMU on my Linux kernel (nothing appears in `/sys/kernel/iommu_groups/` folder).
So I wanted to know if it supports this virtualization technology and if yes, how I can enable it?

Works for me. But, I'm not doing anything cool with it, like GPU passthrough over Xen. I have the same CPU and BIOS, and I think I enabled all virtualization in the BIOS.
I'm sure you've checked cpuinfo:
grep '^flags' < /proc/cpuinfo | grep vmx
... I get one line per thread indicating Intel virtualization is enabled ...
To check if you can DMAR:
dmesg | grep DMAR
... I get:
[ 0.000000] DMAR: IOMMU enabled
DMAR may be disabled by default. If you don't get DMAR in your dmesg, add the following to your boot line:
Different distributions have different methods for editing the boot config, so I'll stop there.
