Do some searches on Arduino lock Fuses. Be WARNED. If you make a mistake, YOU CAN BRICK your ARDUINO!

Read more about fuses while burning the bootloader.

You need to set some fuses and can be done while bootloading.

What you can do is

  1. Copy the existing Uno board and create a new board in board.txt. Change the name of the board.
  2. Set the right fuses in the new copied board. I dont remember the fuse details.
  3. Bootload the uno using another UNO as ISP or use USBAsp
