How to output no-modulated CW

I programmed BLE_TransparentMode to perform RF testing on a custom board equipped with an STM32WBA23.

I want to transmit unmodulated CW, but I can't find a way to do this using HCI commands.

Is there a vendor-specific command to achieve this? Alternatively, methods such as calling an API or modifying registers would also be acceptable.

I found that vendor-specific commands are defined.
I was able to output unmodulated CW using the ACL_HAL_TONE_START command.
