RAK7289 fine timestamping and full-duplex options

I’m testing the RAK7289 gateway. In the product description there are three interesting features listed:

  • Fine timestamping (optional)
  • Full duplex (optional)
  • Listen Before Talk (optional)

From the GUI ( I’m running the WisGateOS_V1.2.2) I can’t find where I can control those options.

Does anybody know how to enable/disable these features??
The hardware should support them as it is equipped with the SX1303 base-band chip.
