Use jetpack 5.1 desktop rootfs

i use jetpack 5.1 with Jetson_Linux_R35.2.1_aarch64 linux kernel,
i use Tegra_Linux_Sample-Root-Filesystem_R35.2.1_aarch64 rootfs,
buf now it don’t have desktop system,
so i use this cmd ./nv_build_samplefs.sh --abi aarch64 --distro ubuntu --flavor desktop --version focal to get a new rootfs .
if now i want to use this cmd ::
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
