Build fails for nrf7002dk/nrf5340/cpuapp/ns — board qualifier not found (Docker Zephyr)

Question

Command: 
 west build -p always -b nrf7002dk/nrf5340/cpuapp/ns LAB_CI --pristine 
 Error: 
 CMake Error at /workdir/zephyr/cmake/modules/boards.cmake:285 (message):
 Board qualifiers `/nrf5340/cpuapp/ns` for board `nrf7002dk` not found.

Valid targets:
 nrf7002dk/nrf5340/cpuapp
 nrf7002dk/nrf5340/cpuapp/nrf7001
 nrf7002dk/nrf5340/cpunet 
 Environment:

Zephyr v4.3.0-rc1 (also reproducible on main )

West v1.5.0

Toolchain: Zephyr SDK 0.17.4

Docker: ghcr.io/zephyrproject-rtos/zephyr-build:main

Host: Ubuntu (CI & local both)

Expected: 
 nrf7002dk/nrf5340/cpuapp/ns should work like nrf5340dk/nrf5340/cpuapp/ns for building non-secure apps with TF-M enabled. 
 
 Observed: 
 The /ns variant is missing for nRF7002 DK, so west build fails immediately. 
 
 Questions:

Is the non-secure variant ( cpuapp/ns ) intentionally not defined for nRF7002 DK?

If not, what’s the correct way to build a non-secure application (TF-M based) on this board?

Should we manually create an nrf7002dk_nrf5340_cpuapp_ns_defconfig , similar to other nRF5340 boards?

Reproduce: 
 docker run --rm -it -v $(pwd):/workdir -w /workdir \
 ghcr.io/zephyrproject-rtos/zephyr-build:main bash -lc \
 'west init && west update && \
 west build -b nrf7002dk/nrf5340/cpuapp/ns LAB_CI --pristine'
