Conflict between Quadspi bank 2 cs Pin pc11 on stm32h750 and sd mmc d3 that crasy is there a way to reasign one of those pin . i want to reasign sd mmc d3 to an other pin ?

Depends on your package, but your options are limited, search the data sheet.

For Dual Bank QSPI in parallel you don't need two CS, other STM32 have an alternate pin for this too (thinking H7Ax)

Could you use SDMMC2 instead ?

Thank you for your help if i have no choice i going to try sdmmc2 but i very hard to build a clear pin out in cube mx in order to make a pcb full functional

How are you configuring QSPI that needs two chip selects?

The most practical use cases require a pair of identical devices on the bus to double the bandwidth. I don't think it can handle two different devices if one is in memory-mapped mode.
