Disable NVMe SSD from BIOS?

I am working on a Jetson AGX Orin Industrial Dev Kit that is using disk encryption. Currently, I am running everything from the Jetpack version 35.4.1 and also have an external NVMe SSD drive for additional storage. During the flashing process, the NVMe SSD is built in to the kernel image.

I was wondering if there is a way to disable this device during boot up by accessing the BIOS? I am able to see the boot maintenance manager and delete it from the list of bootable partitions, but when I press continue and the Orin boot up, it is still seen in /dev/nvme0n1.
I want to ensure it is not detected or loaded at all during bootup and make it inaccessible.

Since it is also a built-in module, is there a way to disable it through kernel configuration?

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

Hi grant.kellogg,

What do you mean about “NVMe SSD is built in to the kernel image”?

Do you want to boot from internal eMMC and use it as roofts?
NVMe is just used for external storage rather than boot device?

Correct, the NVMe is just used for external storage, and I do not boot into it.

Okay, please share the result of lsblk and df -h on your board.

I would suggest you removing the NVMe SSD and run the following command to flash AGX Orin Industrial first.

$ sudo ./flash.sh jetson-agx-orin-devkit-industrial mmcblk0p1

Please format the NVMe SSD as ext4 from your host before connecting to the AGX Orin Industrial devkit.
Then, connect it on the devkit and it should be just used as a storage.
