How to switch external/internal antenna through FW on nRF9160 DK?

[Lulu.C]

Hi,

Programming nrf/samples/nrf9160/gnss sample code (nRF Connect SDK V2.0.0) in PCA10090 development version (0.8.2).
Add the definition of "CONFIG_MODEM_ANTENNA_GNSS_EXTERNAL=n" to prj.conf (switch to non-external antenna).
However, it is confirmed that the measuring point "measure point" of the hardware is in a high level state.
Could you tell me the correct method of external/internal antenna switching through FW setting?

Any help would be appreciated.

Best regards,

Lulu.C
