Drive 1.8v SPI by disabling TI TXB0108 level translators? - Developer Board

Hello,

We need the Jetson Xavier NX to drive a 1.8v SPI. The Jetson Xavier NX Developer Board forces the SPI connections through TI TXB0108 level translators to increase the voltage to 3.3v. The SPI cannot be passed through a second translator as the Jetson Xavier NX cannot drive it.

How can the translators be disabled or removed? Are their any schematics that identify the location of these level translators on the board?

Thank you for your help,
-Hayley

Please refer to the schematic/pcb files of P3509 for that. https://developer.nvidia.com/jetson-xavier-nx-developer-kit-carrier-board-design-package-p3509-a01
