I Want to connect the 32STMF446 with the GFX01M2 display. According to ST it works, but to declare it in TouchGFX so that I can use it?

If you ask one click choice solution = NOT EXIST

GFX01M2 is normal SPI LCD extension, then you need create new project for you STM, and add TGFX custom config.

Thanks,

But how do I get to this choice. Always only the prefabricated boards.

Open CubeIDE click start new project STM32 , select your MCU for custom boards or choice used board F446, configure all peripherals and add software package TouchGFX ...

For other IDE (Keil,IAR...) use CubeMX instead.
