Cannot get BLE module to initialize
The ArduinoBLE library resets the esp32 NINA firmware to BLE mode (default mode is WiFi). But this reset is in ifdefs for specific boards and uses the specific pins to signal BLE mode and for reset of the esp32.
For Nano 33 IoT this pins are 24 (SPI SS) for signal and 27 for reset.
The communication with NINA firmware in BLE mode is over UART named SerialHCI on pins 22 to 25 on Nano 33 IoT.
