Issue or Suggestion Description

I am unable to find how the LCD display is connected to ESP32.
I want to use the Adafruit_ILI9341 library in Arduino IDE. From the code I can see three methods:

/**************************************************************************/

    : Adafruit_SPITFT(ILI9341_TFTWIDTH, ILI9341_TFTHEIGHT, cs, dc, mosi, sclk,
                      rst, miso) {}

#endif // end !ESP8266

The first one uses Software SPI. others - hardware SPI. Since Hardware SPI is faster I want to use hardware SPI. But I don't know if the display is connected via SPI to ESP32.
I found that the default SPI pins for ESP-S3 are:

SPI	MOSI	MISO	CLK.	CS
SPI2	GPIO 35	GPIO 37	GPIO 36	GPIO 39
SPI3	GPIO 11	GPIO 13	GPIO 12	GPIO 10

But I don't know how to match this with:

Also in Arduino IDE SPI (HSPI and VSPI) pins depend on the board and cannot be changed. What board should I use?

Hello, this SPI pin is just the default pin. It can be configured to other pins.

Thank you for the replay, but it is not very clear. "This SPI pin is just the default pin" - which SPI pin? And how it can be configured in Arduino IDE. And also is the display connected via Hardware SPI to ESP32? And if yes what are the pins?
