Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Windows Hello for Business >> "Use a hardware security device" to "Enabled". Prior to v1607 of Windows 10, "Windows Hello for Business" was called "Microsoft Passport for Work" and referred to as such in the policy path.
