in this example
/root/ncs/nrf/applications/serial_lte_modem
I want to build_nrf9160dk_nrf9160 in secure mode
but compile error
#ifndef CONFIG_TRUSTED_EXECUTION_NONSECURE
#error nrf_modem_lib must be run as non-secure firmware.\
Are you building for the correct board ?
#endif
Can I use lte in secure mode
