Lis2dh12 behaviour of i2c peripheral while powered off

Hi.
I'm currently working on an application where I have a lis2dh12 accelerometer sharing an i2c bus with another sensor. These sensors need to be turned off by cutting off the power on the Vdd line. I'm running into issues with communicating with the other sensor while the accelerometer is off, so I'm curious to know how the i2c pins of the accelerometer behave while the sensor is off. More specifically, I'd like to know if the internal pull up of the sensor could affect the i2c line while the sensor is off (is the pull up active while the sensor is off?).

Is there a publicly available electrical diagram of the sensor? Something that has more information than the block diagram included in the datasheet.
