STM32WB55CGUx - CFG_CLI_UART required for FTD

I am trying to set up an STMWB55CGUx device for THREAD. I want to set it up to have no log or CLI interface on any UART. When I select the FTD THREAD application type the CFG_CLI_UART setting is still requiring a UART to be able to auto generate a hw_uart.c file that is useless to me. This essentially blocks off a UART without editing files that could be overwritten via a re-generation. 

Is there any fix apart from manually editing auto-generated code? 
STM32CubeIDE v1.18.1
STM32CubeMX v6.12.1

Hello ​@ABStiltz 

Let me thank you for posting and welcome to the ST Community.

I recommend that you use the last STM32CubeMX Version 6.17.

You can download it through this link: STM32CubeMX | Software - STMicroelectronics

Thanks.

Hello ​@ABStiltz 

Further to your comment, you need to enable CFG_HW_LPUART1_ENABLED and CFG_HW_USART1_ENABLED parameters and then set CFG_CLI_UART as hw_uart1 or hw_lpurat1.

Thanks.

My question was not how do I get it working, but why do I have to set the CFG_CLI_UART when I specifically only want FTD and not FTD_CLI? This essentially renders a UART pointless no matter what I choose.
