I don't think you can, at least, not as yet.

The only version of O (not officially "Oreo", and may not actually be Oreo) is the Alpha (before Beta) version for Nexus and Pixel devices. Be patient. If your device has not yet even gotten Nougat, Redmi may not even be releasing O once it's released by Google.
