STM32WB05xN changing hardware configurations

I am planning to use the STM32WB05KN as a network coprocessor for a STM32U0. The Nucleo board has both LSE and HSE populated, but since my PCB is space constrained, I would like to use the internal oscillators instead of external and also turn off SMPS. My understanding is that the provided prebuilt DTM firmware would not work without these components and I would need to change these settings:

The document this points to (AN5503) describes steps to rebuild the firmware using the BlueNRG GUI but says to use CubeMX for STM32WB0 devices:

However, CubeMX does not have support for directly interfacing with WB05xN devices as far as I know. In this case, how can I change the settings? Thank you!

Hello @yichen15922 

What is document mentioned on the first paragraph of your answer. For framework and HW configurations, i suggest you have a look at the STM32WB05xN Bluetooth® LE network and radio coprocessor framework & HW configurations, parameters - stm32mcu.

Best Regards.
