How do I configure my SX1262 module to use DIO2 and DIO3 appropriately? I can't find any documentation on how to define these necessary settings.

I would use the settings from another board and adapt eg MeshADV:

      "bus_id": 0,
      "cs_id": 0,
      "cs_pin": 21,
      "reset_pin": 18,
      "busy_pin": 20,
      "irq_pin": 16,
      "txen_pin": 13,
      "rxen_pin": 12,
      "txled_pin": -1,
      "rxled_pin": -1,
      "tx_power": 22,
      "use_dio3_tcxo": true,
