How can I set STM32CubeIDE in the following way

Preamble: consider I have an STM32F4 Discovery Board.

Hi,

STM32CubeIDE offers a very good interface and opportunities. However, I am type of a person who wants to actually see each step. So, I want such a configuration that, only the minimum set of required files will be added to the project folder, and then I will code everything by mysel. I mean no HAL or LL libraries will be added etc. I just want that file in which register addresses are defined, (it was something like `stm32f40xx.h`) . And then I want to write my code into a fully clean empty(no System clock config function or gpio_init functions) `main.c` and and build the project, and load it into my board. I could not configure CubeIDE in that way. I tried somehow changing the advanced project settings of a STM32 Project in such way it will not overwrite those functions to main.c but I could not do it. Then I tried to just open a C project but this time I could not achieve to load the code into my board and debug. Because I could not find a place to choose target device.

So, can you please provide me a set of steps to set CubeIDE in this way?

Any non CubeIDE way of approach also would be appreciated.

Thanks.
