I am working on interfacing MicroSD card with STM32H757I-EVAL. I am following the same steps to setup and configure SDMMC1, as mentioned in this video https://www.youtube.com/watch?v=-0kFwp0ao6k @2:56 but there is DMA setting option under SDMMC1 configuration. I am not getting this option to configure. What could be the reason? I have attached the image of IDE environment.

You're using a different chip. The SDMMC peripheral has changed quite a bit between those two. On the H7, it has an internal DMA which I suspect is always enabled in CubeMX. Look at the IDMAEN bit after configuration.
