How to change default device_eui, epp_eui, app_key from the program?

I have my custom project on the LoRa RAK3172 module. To set the DevEui, JoinEui & Appkey I have to set default as

uint8_t default_dev_eui[8] = {0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01};
uint8_t default_join_eui[8] = {0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01};
uint8_t default_app_key[16] = {0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01};

Which eventually gets stored in the NVM structure and then in the nvm_backup structure. But is there any way how these can be changed without any change in the code?

I tried to pass the SeNVM structure into NVM structure. Which initially saves the data, but the nvm & nvm_backup overwrites the default data. Is there any function through which I can do it correctly?

With AT commands. See here.

AT+DEVEUI=1122334455667788
OK

AT+DEVEUI=1122334455667788
OK

AT+APPEUI=0102030405060708
