How to setup USB3.2 for AGX Orin at R35

use USB3.2 Lane 2 which the port is map USB2-3。
my pinmux set ：
usb_vbus_en0_pz1 {
nvidia,pins = “usb_vbus_en0_pz1”;
nvidia,function = “rsvd1”;
nvidia,pull = <TEGRA_PIN_PULL_UP>;
nvidia,tristate = <TEGRA_PIN_ENABLE>;
nvidia,enable-input = <TEGRA_PIN_ENABLE>;
nvidia,io-high-voltage = <TEGRA_PIN_ENABLE>;
nvidia,lpdr = <TEGRA_PIN_DISABLE>;
};

                    usb_vbus_en1_pz2 {
                            nvidia,pins = "usb_vbus_en1_pz2";
                            nvidia,function = "rsvd1";
                            nvidia,pull = <TEGRA_PIN_PULL_DOWN>;
                            nvidia,tristate = <TEGRA_PIN_ENABLE>;
                            nvidia,enable-input = <TEGRA_PIN_ENABLE>;
                            nvidia,io-high-voltage = <TEGRA_PIN_DISABLE>;
                            nvidia,lpdr = <TEGRA_PIN_DISABLE>;
                    };

Although the problem has been resolved，But I don’t know the principle。
I replaced the/boot/dtb/xx. dtb file, it doesn’t work，It only works when I redeploy the system（./flash xxxx mmcblk-p1）
