nRF9161 - RTT disabled in Kconfig?

I just fired up our most recent custom boards with nRF9161-LACA's, and tried to compile modem shell application for RTT.

I noticed the RTT is disabled because HAS_SEGGER_RTT (defined at v2.6.1/zephyr/modules/segger/Kconfig:7) returns "n"

Looking at the files, it seems CONFIG_SOC_NRF9161_LACA isn't included in the CONFIG_SOC_SERIES_NRF91X:

What's the simplest workaround until Zephyr is updated?

Current SDK is 2.6.1

EDIT: I see the CONFIG_SOC_NRF9161_LACA selects CONFIG_SOC_NRF9120=y, so the problem is somewhere else...

EDIT #2, nRF9161DK compiles with RTT enabled, so the issue is probably in my board files,
