Configuring temperature sensor

Hello,

I'm trying to configure the internal temperature sensor but have no idea ... 

My board selection is raytac_mdbt53_db_40_nrf5340_cpuapp and, on nRF Kconfig GUI, I cannot check "nRF Kconfig GUIでnRF5 Temperature Sensor" as it is gray-out.

When I try raytac_mdbt53_db_40_nrf5340_cpunet instead, I am able to read the temperature value.

Could you advice how I can cope with this situation?

Thank you in advance!
