Why NC is written on PF0 and PF1 pins of NUCLEO H743ZI2 though it is connected to microcontroller?

I am working on NUCLEO H743ZI2 and I want to use PF0 and PF1 pins as I2C2. But on nucleo board NC is written on these pins. Can I use these pins as I2C2?

    PF0 and PF1 are connected. Silkscreen has been updated in later revisions.

    How come you have a revision MB1364B board. Mine is revision MB1364C with a revision V chip. Anyway, have a look at the attached schematics. Revision B no revision C yes, unless you put the external oscillator.

    I'd be inclined to trust the board and assume those pins are not connected.

    Set them up a GPIO outputs and see if you can change them, or probe directly to be certain. Schematics are also available.
