Usage of Adafruit Blefruit with Suchergebnisse Arduino Nano 33 BLE

i would like to use Adafruit Bluefruit Lib instead of ArduinobLE lib.
Does someone know how to do that ?

I ow that it is possible by changing Bootloader is this the only possibility.
Because by changing bootloader it is identified as Adafruit feather board, that has slightly different hardware definitions. If possibly i would like to keep board identity as Arduino nanao ble 33

Thanks in adcance.
