Portenta H7 dual power supply

Official Hardware Portenta Family Portenta H7

Hello everyone

I would like to use an Arduino Potenta H7 and use a double power supply for it (using pins of Arduino Portenta H7 and another power supply using an external POE).

I would like to make sure that when I use both the POE and the power supply at the same time (using the Portenta H7 pins), the two power supplies do not give any problems.

I would like to use a solution that allows me to interrupt the + 3.3V of the POE if I already use the + 3.3V power supply via the Portenta H7 pins.

Would it be possible to do all this?
