J44 Hookup question

Hello!

I’m trying to find the schematic for J44 of the A02 board (single cam connector version). I have an FTDI serial connector shown below (pg 11-12 for connector pinout):

It looks like it’s pin to pin compatible with J44 of the A02 board but it does show the Vsupply as NC. Does this mean that the pin on the schematic actually has 3.3V or is it floating (in which case I can use this cable without damaging anything)? Unfortunately, I can’t find a schematic that even makes reference to this connector (which is problematic in and of itself).

Let me know when you get the chance. Thanks!

J44 schematic is as below:
