hello jetson_user,
you don’t need those tegraflash commands to generate signed and encrypted binaries.
please enable the flash scripts, adding --no-flash options into the commands line.
for example,
$ sudo ./flash.sh --no-flash -k kernel-dtb jetson-tx2 mmcblk0p1
please refer to below, it will calling all necessary python scripts to complete the process.
*** Signing tegra186-quill-p3310-1000-c03-00-base.dtb ***
./tegraflash.py --chip 0x18 --cmd "sign tegra186-quill-p3310-1000-c03-00-base.dtb" --skipuid

after that,
you’ll also found it generate signed and encrypted binaries to your local host machine.

you may copy this binary to your remote target, using dd commands to update the partition without flashing.
thanks
