Since July 28, 2016, all new device models, lines or series (or if you are updating the hardware configuration of a existing model, line or series with a major update, such as CPU, graphic cards) must implement and enable by default TPM 2.0 (details in section 3.7 of the Minimum hardware requirements page). The requirement to enable TPM 2.0 only applies to the manufacturing of new devices.
