Yeah on that specific board it looks like it’s included . I was just going from experience. I just wired such a sensor to an Arduino the other day and I was having problems without the pull up. I was seeing garbled data packets on the data line.
edit: you can easily confirm this by measuring the resistance between VCC and Data on the sensor.
Just dealing with Dell about a Latitude 5520 wjth extended warranty.
External displays turning off and on again and system freezing up all the time even after reinstall. And Dell says it's because of wear on the USB-C ports that is barely visible and not covered.
