BQ25120A: How to set ILIM, ISET, IPRETERM of BQ25120A?

Part Number:BQ25120A

I am developing a wearable product using BQ25120A.

Question 1)
I would like to connect ISET, ILIM, IPRETERM 3 pins directly to GND without using resistors. Can I set the values in the Register via I2C?

Question 2)
If I connect from ISET, ILIM, IPRETERM 3 pins to GND through resistors,
Can I set the values of ISET, ILIM, and IPRETERM registers through I2C?

Question 3)
I do not use NTC, so I want to open the TS pin. Can I open the TS pin?

Thanks,

Sunbae Yim.
