Flashing uefi on orin nx

I have a SOM flashed and have all installations on it, but it is taking a lot of time for booting (around 1 minute), so I want to make changes in uefi and flash only uefi on it to reduce boot time.
SOM: Orin NX
jetpack version: 5.1.4
DTB: tegra234-p3767-0000-p3509-a02.dtb
Command used to flash:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1
-c tools/kernel_flash/flash_l4t_external.xml -p “-c bootloader/t186ref/cfg/flash_t234_qspi.xml”
–showlogs --network usb0 p3509-a02+p3767-0000 internal

Can you provide me command to flash UEFI only? Is it possible? And I don’t want to loose my installations like opencv build from scratch on SOM.

Hi,

Our recommended way is to flash qspi including uefi.
Below is the command:

Thanks
