LL Driver Support for SPI on STM32H743ZI

I am working on a project using the STM32H743ZI microcontroller.
I want to implement SPI communication using the LL (Low-Layer) drivers instead of HAL.

:question_mark: Can you confirm whether the STM32H743ZI supports LL SPI driver APIs like LL_SPI_Init, LL_SPI_TransmitData8, etc.?

Also, are there any specific settings or header files (like USE_FULL_LL_DRIVER) required to enable these LL functions in STM32CubeIDE

Does STM32H743ZI support SPI communication using LL drivers? I’m using STM32CubeIDE.
SPI1 is enabled, but LL_SPI functions are disabled unless I define USE_FULL_LL_DRIVER.
Is this the correct way to enable LL SPI support?

hi I am trying to stm32cube ide ,Enable the LL _spi but stm32h7xx_ll_spi.h file not enable the functions . why ?
