SGMII connection to UFS module in IGX T5000 reference schematic

Hi Team,
PFA image of UFS storage in IGX T5000 carrier board schematic.
Could you please tell me why is the SGMII connected to M.2 UFS section?
What purpose does it serve?

NVIDIA designed a board for FSI-SGMII and UFS that plugs into that M.2 Key-M connector. If your design only uses UFS, you can ignore the SGMII signals.
