LA915-928A on RAK11310

I’m having problems connecting my device to the LoRaWAN network in Brazil, I ended up checking the band and found this value in the selected band, I wanted to know if there is any value that I can use in the wisblock RAK 11310 to make it work.

LoRaWAN region LA915 is not supported by the open source LoRaWAN library SX126x-Arduino.

Can you share the LoRaWAN regional specifications for LA915.
