Primary battery for RTC for Jetson TX2

Hello, I’m working with Jetson Tx2 and I put a 3V primary battery in series with diode instead of superCap, but it seems like the battery always drains some current, and it doesn’t matter if I enable or disable the BBCEN bit on max77620, nor any other bit in CNFGBBC register ( except of BBCVS - then it drains more than usual ) My question is, how can I put the primary battery with diode instead of supercap and not have current drains when the VIN is on? Is there any other register I need to c…

the PMIC datasheet for MAX77620 explains how to configure.
