Yes you can. You need to install the firmware ESP32_BLE_REV0 (rev 1) or ESP32_BLE_REV3 (rev 3). The rev0 or rev3 refers to the Hardware Revision number. For example, below I have a Revision 3 (REV3) hardware and this can be seen when flashing the firmware using nanoff.

Example: flashing with Bluetooth firmware

nanoff --target ESP32_BLE_REV0 --update --serialport COM3

Connected to:
ESP32 (ESP32-D0WD-V3 (revision 3))
Features WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Flash size 8MB unknown from ST (manufacturer 0x32 device 0x16407)
PSRAM: undetermined
Crystal 40MHz

Run the command below and let nanoff decide. The picture below will tell which version of the hardware you are having.

nanoff --platform esp32 --update --serialport COM3
