Does my C7 have integrated TPMS or will I need valves/sensors?

Hi there I'm looking to change my wheels eventually but it flagged up on the site that I may need TPMS valves.
Was hoping this will not be needed as it would be built into the car of a modern car, can someone she'd light on this?
Thanks

Standard TPMS is indirect so runs off ABS.
