STM32CubeMX for the STM32WB09 -CMSIS OS AND BLE Strange behaviour

"I am generating code using STM32CubeMX for the STM32WB09, aiming to implement BLE with CMSIS-OS.

I am facing an issue where, even after explicitly disabling the Sequencer when enabling CMSIS-OS, CubeMX still generates code that relies on the Sequencer. This results in an application with multiple errors.

Upon checking the official examples at https://github.com/STMicroelectronics/STM32CubeWB0, I noticed that the projects utilizing RTOS do not seem to rely on CubeMX (the .ioc files are missing).

Is there a known limitation or bug regarding this behavior in CubeMX?"
