Why can't i enable SDIO in CubeMX on NucleoL452RE(P) while it is possible on the corresponding spare MCU

Hi,

I bought some NUCLEO-L452REP (wich include STM32L452RET6 MCU with an SMPS support) particulary because of its SDIO interface.

But this interface is not available (not displayed) in CubeMX for the nucleo while it is available if I choose the spare MCU (L452RET6) in the board/MCU selector.

Is it a bug or a constrain ?

(EDIT : The prblem isn't on the Nucleo vs MCU. The L452RET6P hasn't SDIO interface available in cubeMX but the L425RET6 (not P) has one. The datasheet seems to say that both MCU have SDIO interface)

Cube MX with the MCU selected :

The LQFP64 SMPS version is missing a PD2 pin, which is required by the SDMMC. Therefore, it is not usable on this device.

It's also mentioned here in the datasheet:
