Pixhawk 6X not showing battery stats

In QGroundControl, can you check the start output in Analyze Tools → MAVLink shell: then type dmesg.

I’m looking for any ina_ output which is the driver starting.
In theory, it should auto-detect the module by default but it looks like that’s not working.

What’s your PX4 version?

You can also try to force the start of the driver using the params SENS_EN_INA226, SENS_EN_INA228, SENS_EN_INA238 depending on which one you have.
