Despite its name, the regulator vcc3v3_pcie30x1 has nothing to do with pcie30x1. Instead, it supply power to VBAT1-5 on the M.2 KEY B port as seen on page 8 of the schematic [1]. pcie30x1 is used for the mini PCIe slot, and as seen on page 9 the vcc3v3_minipcie regulator is instead related to pcie30x1. The M.2 KEY B port can be used for WWAN USB2 modules or SATA drives. Use correct regulator vcc3v3_minipcie for pcie30x1 and enable sata1 node to fix use of SATA drives on the M.2 slot.
