TPS6518 Default Setting for DCDC1

Hi Sir

We use Non-TI MPU with TPS65218 PMIC  for design. And we would like to set the DCDC1 default voltage of TPS65218' as 1.05v. while booting.

But the default value of DCDC1's register  is set 1.1v. 

Does TI have any suggestion to  modify the DCDC1's output after PMIC is power on? 

Is it available to modify the internal EEPROM of TPS65218 ? 

thanks for reply.
