Changing SD signal voltage level in jetson nano

Hello there,

We are using a carrier board which is compatible for both Jetson nano and Xavier NX production modules in which we observed only in NX som the SD_Signals (Clock + Data) transferring with a magnitude of 1.8V , But while using NANO module the SD_Signals are in the level of 3.3V we want to change the level of voltage from 3.3V to 1.8V (UHS1 mode).
we found that the nano is compatible for 1.8V

Jetson nano data sheet; SD spec.

please guide us to change SD_Signals magnitude from 3.3V to 1.8V

There is no Hardware changes implemented while changing NX to nano module.

Try to add only-1-8-v and give a 1.8 v regulator to your vmmc-supply under your device tree.
