Does it still have the built-in operating system? If so, is this required, or can I replace it and run my own bare-metal firmware?

- gh02t 10y agoIt still has a built in RTOS like the 8266 and no I don't think you can replace it. Not easily anyway, Espressif could probably do it but I don't think users really are able to. Your stuff is running bare metal though - your code is linked directly into the same binary payload as the RTOS. One of the major selling points of the ESP32 though was that it is dual core, so that you can have one core dedicated to servicing your code and the other to dealing with keeping the radio stack alive and such.
