STM32 Nucleo support for 1.8V

Hi

I'm using the STM32H755ZI board which has the option for 1.8V DVDD (using JP5).

Does switching DVDD to 1.8V from 3.3V limit the functionality of the board in any way ?

Are the interfaces (CAN, I2C, SPI, UART etc) still functional at 1.8V ? 

Thanks in advance for any help
