Over the Air modem(AWS MQTT) Firmware update 1.2.3 to 1.3.1

Hi,
I want to update the modem firmware devices(in the field).I am using nRfconnect sdk 1.5.0 and hardware is brf9160 SICA B1 .
current modem firmware is 1.2.3 .
I tried to https://devzone.nordicsemi.com/f/nordic-q-a/81643/full-modem-firmware-update-for-modem-v1-3-0/357363#357363.

but I am unable to update.
I am using AWS (MQTT) for FOTA updates.

CONFIG_DFU_TARGET=y
CONFIG_DFU_TARGET_FULL_MODEM=y

but its not enabling the DFU_TARGET_FULL _MODEM.

build_path\zephyr\.config

DFU configuration

#
# DFU
#
CONFIG_DFU_TARGET=y
CONFIG_DFU_TARGET_MCUBOOT=y
CONFIG_DFU_TARGET_STREAM=y
# CONFIG_DFU_TARGET_MCUBOOT_SAVE_PROGRESS is not set
CONFIG_DFU_TARGET_MODEM_DELTA=y
CONFIG_DFU_TARGET_MODEM_TIMEOUT=60
# CONFIG_DFU_TARGET_LOG_LEVEL_OFF is not set
# CONFIG_DFU_TARGET_LOG_LEVEL_ERR is not set
# CONFIG_DFU_TARGET_LOG_LEVEL_WRN is not set
CONFIG_DFU_TARGET_LOG_LEVEL_INF=y
# CONFIG_DFU_TARGET_LOG_LEVEL_DBG is not set
CONFIG_DFU_TARGET_LOG_LEVEL=3
# end of DFU

Please guide me about the necessary configuration.

If you look at the warnings (which should be treated as errors, unless you know what they mean, and are okay with the error. One example where Kconfig warnings might be okay is if it complains about log…

What error do you get when trying to open the file?

I don't think we have tried using an SD card as external storage for full modem updates before. However, I cannot think of any reasons why it wouldn't work. But, if you try to use our existing libraries for full modem updates, you might have to make some modifications for it to work with an SD card instead of an external flash chip.
