ESP32-MINI-1 Single UART for firmware and AT?

I'd just like to ask this, because it has implications for our layout:

It's been established that in PROGRAM mode, firmware is uploaded via pins TX/RX 36/35
The default assignments for the AT mode(for MINI-1 Bin) are TX/RX 22/19

Would it be possible to re-assign pins so that for AT mode, pins ...

Pin confusion on ESP32-MINI-1 Module

We've ordered the ESP32-MINI-1 Module (not the development board, just the module), and I am very confused about which UART port is connected to which pins.

The datasheet shows:
U0RXD (GPIO3) on pin 35
U0TXD (GPIO1) on pin 36
U0CTS on pin 32
U0RTS on pin 33

U1RXD on pin 25
U1TXD on pin 26 ...

What is loaded to the ESP32-MINI-1 Module

We have ordered the ESP32-MINI-1 Module (Not the development board, JUST the module)

* Does the module come with the AT Firmware Loaded?
* If not, does the module come with firmware loaded to allow me to use the flash_download_tool?
* If not, do I need to load something to the module using the JTAG ...
