@BBenn , what is it that you are attempting to do exactly?
To work with your STM32F769I-EVAL kit + TouchGFX?
If yes, suggest to NOT start with CubeMX but rather launch TouchGFX as a stand alone -> select the STM32F769I-EVAL target -> create your GUI story board -> proceed to use the gcc compiler which is applied behind the scene to compile your code.
Moving forward, to review the code that is auto-generated, you can launch the IAR 8.x project and use the IAR compiler to view the source code and folder structure. The IAR compiler does not require to be licensed since you will only be using the compiler as an editor. The gcc compiler will be used for all compilation.
From (more) days of trial and error, know that CubeMX will break your project if you attempt to allow it to modify any IOC project file linked so some of these kits. For now, you do not have the IOC generator as the TouchGFX template is on 1.1.0 but we have wasted days on trying to fix STM32F769I-DISCOVERY target using v2.0.0 template. This template is what you really require but for your target kit but as noted, once CubeMX touches this IOC file and you select GENERATE CODE from CubeMX, the working project will break.
For now, you may want to wait or be very patient to review what gets broken and/or generated by the gcc toolchain that you can use under CubeMX. Using the TouchGFX tool, you should be able to manually modify to use additional IP that CubeMX would have generated.
