Using arduino ide how can I connect to the device without usb port? Is there a serial to usb adapter? Or another method such as bluetooth, ethernet or wireless?

PoESP32 is a unit and meant to be controlled via Groove serial connection using AT commands.
May I ask what is the reason you'd like to modify the preinstalled AT firmware?
Note: J2 is internal and not populated.
Note: the preinstalled internal firmware can be altered / replaced using Arduino IDE. But please be aware that restoring the preinstalled AT firmware requires the ESP-IDF build environment (which is different from the Arduino IDE). Preinstalled AT firmware source code and build instructions can be found here.
