No single video output can provide that (no video standard exists for embedded alpha channel). You would have to use a system that supports something like the Decklink Duo.

But... if you are asking if there is some other (non-BMD product) that does such a thing (one thunderbolt port but has two independent video channels)... I have not heard of one. Good idea though.

The Ultrastudio 3d and Ultrastudio 4k both have dual SDI outputs to be used for Alpha keying. However you will need special software to "split" the signal to each output. We use ProPresenter 5 which has an alpha keying module that does this.
