Using MicroSD UHS-II With Xavier/TX2 NX & Nano

Hi,

Small but important question: If I designed a custom carrier board, one that would fit the TX2 NX, Xavier NX and Jetson Nano. Could I add a MicroSD UHS-II card slot on the carrier board, and could the Jetson devices be able to Read and Write to the UHS-II card at UHS-II speeds? Or would the Jetson devices R/W to the card at lower speed?

Please refer to their module datasheets in DLC which indicates that “Support for SD 4.0 Specification without UHS-II”.
