Ethernet Modes Supported for STM32H757XI

As given on datasheet this microcontroller can support 10/100 Base T Ethernet. Is there any probability that this microcontroller supports Gigabit Ethernet and if yes, please provide the recommended circuitry for the same.

Not possible.

H7 ETH MAC supports 100M max.

Check the STM32MPx series, (some of) these have Gigabit MACs.

Edit: maybe there's a solution with an extra IC, something like "SPI-to-Gigabit".
