Support of STM32F4 Discovery borad with SDIO 3.0 Card

The SDIO on STM32F407G-DISC1 Discovery board is full compliance with SD I/O Card Specification version 2.0 . Is it possible to interface an SDIO 3.0 card with this STM32 MCU ?? Is there any good any tutorial or examples on the interfacing of STM32 and I/O cards?

Bunch of schematics of working designs on EVAL and other DISCO boards.

Bunch of working code examples under HAL/Cube trees, review?

Got familiarity with the Card Specs, work through the SDIO or SD-MMC examples and understand what's going on.

Would imagine modes of operation might limited, but backward compatible.

Use DMA, polled operation is marginal and prone to break with bus/interrupt loading.
