How to enable SPI interface for WLAN instead of UART

I'm working with ESP32 WROVER KIT with attached LCD Display.
It's datasheet suggest that it supports SPI interface.
However, WLAN communication happens over UART.
Is there any reference document to disable UART and enable SPI communication for ESP32-WROVER-KIT

I don't understand your question... the kit has WLAN, UART, SPI and more peripherals, and you can use all of them at the same time dependent on the firmware you put into the devboard.

Thanks for the quick reply.
I want to enable SPI interface for WLAN data traffic.
It has SPI flash but not using SPI interface for WLAN traffic.
Using SPI interface will result in reduced WLAN throughput in general.
I want to know if there's any documentation to enable SPI interface for WLAN data traffic(possibly with any hardware changes required)

Do you mean you want to use the AT firmware with SPI?
