How to control the discharge FET during charging state

Hi,

I got a question with bq78350. Since I use the seperate path for charging and discharging, so I want to control them seperately. But as I found, the discharging FET is always turned on when the battery is in charging state (with charging current), I cannot turn it off unless I turn off both FETs at the same time. The same situation also applies to charging FET when the battery is in discharging state. Who can tell me how to control the charging and discharging FET seperately? Any settings need in the bqstudio or any modifications need in the firmware? I really need this feature.
