BC66 cert to NVRAM

Hi there,

I am interesting about a posibility to write client certificate in NVRAM on BC66-TE board?
The certificate is needed to connect to IoT platform with SSL. All related code is handled by external MCU (Arduino UNO), because of touchscreen display in the solution. On this external MCU no space to store the cert, when BC66 have enough. After cert will loaded to NVRAM it is need to be able to use it via AT-commands through UART.

Appreciate any suggestions with this regard.

BC66 not have file system
