I might be missing a trick here, but it seems that most (if not all) DISCO / EVAL boards expose the same I2C bus externally that is used to communicate with onboard peripherals.
This makes perfect sense with DISCO boards as they are small / low cost. But I had hoped that on the EVAL boards there might be an option for one of the free I2C busses to be exposed. And to be able to dedicate one I2C bus to the M4 and another to the M7, for example.
I don't seem to be able to find one with an alternate pin function set that allows this. Am I missing something obvious?

Eval boards have jumpers to disconnect external transceiver, so there should be options there. Or use the poor man's sw bit bang solution, in this case many gpio candidates....

DISCO / NUCLEO boards would probably expose via the ARDUINO SHIELD, run OLEDs and GNSS receivers from there,and on H7 board
