BQ27Z746: How to program golden image to BQ27Z746 with I2C without bqstudio/ti mcu?

Part Number: BQ27Z746
Other Parts Discussed in Thread: BQSTUDIO

Tool/software:

Hi there, 

We have to use BQstudio to program the proper chemistry and any other parameter that is not allowed via I2C. From there we have to extract the golden image via BQStudio. My question is, Is there a guide how to flash the golden image to the BQ using I2C with non TI mcus?  

Also from my understanding, we cannot write chemistry id via i2c, only through bqstudio. So does the golden image contain the new chemistry ID?
