modify /boot/extlinux/extlinux.conf
$FDT /boot/camera/tegra194-p3668-all-p3509-0000.dtb

NX startup cannot enter the desktop
Is there any way to do that without flash machine !!!!

Now there are still important files in NX, I forgot to back them up

Check with uart serial console.

FYI, if you can’t get access with serial console, then you can still clone, edit the content back on the clone, and then reflash using the clone. There is a good chance the serial console still works.
