Detecting and To be enabling SD Card Mount slot in Javier NX module with custom carrier board

I am setting Jetson NX Module and Custom Carrier Board with microSD Card.
But, Jetson Linux System does not detect micro SDcard on SDcard mount.
I can figure out that i need to modify device tree block and rebuild dtbs.

The documents that i shared point to modify state in dtsi.

Remove state in /hardware/nvidia/platform/t210/porg/kernel-dts/porg-platforms/tegra210-porg-pwm-fan.dtsi

tach_gpio = <&gpio TEGRA_GPIO(Z, 2) GPIO_ACTIVE_LOW>; /* TEGRA_GPIO_PZ2 */

Add states in sdhci node in /hardware/nvidia/platform/t210/porg/kernel-dts/tegra210-porg-p3448-common.dtsi

status = "okay";
cd-gpios = <&gpio TEGRA_GPIO(Z, 2) 0>;

As document is for jetson Nano series, we can’t use this method.
So, I need to know how to enable SDcard mount slot as i modify device tree.
Let me know how to change and apply.

Thank you!

You can search sdmmc3 as keywords on NX forum first.
