to your question -

VDDIO_A - VDDIOA is the supply to for Ports 9 and 10. It must be connected to VDDA on the PCB when present.

VCCBUCK2 - Similar to VRF in other packages, VCCBUCK2 is the output 2 of internal SIMO. Connect it to VDCDC in schematic.

GANT1/GANT2 - the ANT shielding GND. Connect them to ground.
