How to use initrd tool in jetpack 4.6.1

Hello all,
We are using the Xavier nx module and want to use the initrd tool.
However, the following error will be reported:

cx@cx:~/plink/flash/xavier-tx2/32.7.1/Linux_for_Tegra$ sudo ./tools/kernel_flash/ --external-device nvme0n1p1 -c ./tools/kernel_flash/flash_l4t_nvme.xml -S --showlogs y-c6-xavier-nx-3271 nvme0n1p1
/home/cx/plink/flash/xavier-tx2/32.7.1/Linux_for_Tegra/tools/kernel_flash/ --no-flash --external-device nvme0n1p1 -c ./tools/kernel_flash/flash_l4t_nvme.xml -S --showlogs y-c6-xavier-nx-3271 nvme0n1p1
Please install the Secureboot package to use initrd flash
Cleaning up…

Follow the Jetson Linux Developer Guide as shown below:

However, when I searched in the download center, I was told that the corresponding package was not found.

I can’t find a corresponding package on this screen,
Jetson Linux R32.7.1 Release Page | NVIDIA Developer

Where can I get the corresponding Secureboot package?

Hi chen.xi,

Are you using the custom carrier board for Xavier NX?
Could you help to use latest R32.7.3 to verify?

and you could download secure boot package in the release page as following:

Thank you for your reply. I searched the download directory of SDKmanager and found the compressed package I need in it. In addition, I cannot upgrade to R32.7.3 at present.

In addition, during the process of using the initrd tool, a new problem was encountered with restoring the system image backed up by backup.
