Bluetooth 5 Long Range

Is there someone who finally managed to change the tx power and the modulation mode to CODED PHY using Arduino Interface ?

I have tried to change the registers themselves using NRF_RADIO->TXPOWER and NRF_RADIO->MODE but it seems the ArduinoBLE library writes over the txpower and mode registers again and again...so it is impossible to change them by hand in the arduino code, maybe there is a part of the library code or in the mbed part in which it is possible to change the default value of these registers ?

Thank you,
