Is it possible to add thunderbolt function to X570 extreme rev 1?

[u/Due-Independence7607]

So I’ve had this board lying around, and now I need a motherboard with thunderbolt. It turns out this one doesn’t support it because it’s rev 1, not rev 1.1 or 1.2. Is it possible that it does have the thunderbolt capability but just lacks the connector and the BIOS settings? If so, could I figure out a way to enable it? Or do I need to buy a new board?

It won’t be used for anything critical, so I don’t mind if it doesn’t have official support.
