Can I use and external power supply and USB at the same time

Yes, you can simultaneously connect external power supply and USB. As explained in one of the answers, that you linked, the Arduino chooses it''s power input through the supplied voltage on Vin/barrel jack. Vin has no direct connection to the VUSB, so the USB port will not get any voltage from the external supply, thus it does not get damaged.

Powering up an ESP32 with external power

One was to connect a 9V battery to the 5V pin of the board directly and have the default ESP voltage regular to control the voltage. PS: I would have to do that in parallel connection since I already have a module connected to that pin. Second was to use an external voltage regulator and connect that to the 3.3V pin on the ESP board. With a
