Using Arduino Nano 33 BLE with Adafruit Bluefruit lib

Hardware Nano Family Nano 33 BLE
1

Hello,
due to some current limitatons of ArduinoBLE Lib i wanted to use adafruit Bluefruit lib with arduino nana 33 nle.

I knew it is possible by changing the bootloader, by means arduino nanao acts as adafruit feater 52840 after that.

But: I wan't to use bluefruit without changing Bootloader to keep identity of the board.

Any experiences or hints about that

Thanks in advance
