Is Thunderbolt 4.0 currently available on ANY ATX motherboard?

There is so much online boasting the stellar features of TB4, well, sounds good to me, but is it available?

I see peripherals, and perhaps some laptops, yet am trying to put together a new desktop and want this feature if it's available.

If it's not available, I'll just move on. If there is something I can do to 'be ready' for it, please advise.

If you know of ANY ATX MoBo with it, please let me know. (Maybe this is a 2021 thing - I dunno)

TIA

"We have also been told that the Z590 motherboard series with Thunderbolt 4.0 support will be announced later this year so expect more information on Rocket Lake CPUs in the coming months."

If true, the implication is that it isn't yet available on Z390 or Z490 chipset motherboards.

Z 390 is the older socket 1151; Z490 is socket 1200.

I have no idea about AMD.
