M2.M nVME connector Polarity Inversion

I have looked at the gerbers for the latest Orin Nano devkit, and the nVME TX/RX lines have polarity inversion on the gerbers.

But the schematics in the devkit resources do not show any inversion, am i looking at the wrong schematics?

MY M2.M connector is on the rear side of the board, so i will need to invert polarity of the TX/RX lines.

I am no expert on these nVME SSDs, from my research they support lane inversion…

Every PCIe lane supports polarity inversion. In multi-lane PCIe configuration, each lane can have polarity inversion enabled for better PCB routing as needed.
