How do I remove Micropython and restore the original firmware which came with the board out of the box?

Unless you saved a copy of the original firmware someplace, you'll need to find a copy online someplace, and install it according to the instructions for the original firmware.

I searched online and I found this on the official website
https://www.espressif.com/en/products/h ... /resources
Under the AT section, there are many firmwares for the esp32. I downloaded the latest version for my WROOM-32.
When I extracted its content. I found multiple binary files. Eg: bootloader.bin, factory.bin.
My question is which file should I flash via esptools. Can you tell me how to flash it? Or point towards a guide which can help me restore the original firmware?
Thank You.

For such generic ESP32 questions I would recommend cunsulting the ESP32 documentation and the official Espressif forum.
You will find all the answers there.
