Chosen Solution
I am currently located in Germany, which uses a local keyboard layout. As a programmer, I would like to have a US (ANSI) layout (UK (ISO) keyboard would also be ok) for my MacBook Air (late 2020), how can I go about doing it?
To start with the uppercases between the US and ISO systems are different! As the Return and shift keys are physically different. So the only way to convert your system is replacing the uppercase assembly which I don’t think is worth the risks as these systems are so new we still can’t get the parts and if you review these guides you’ll see its not easy trying to take the battery out to swap over MacBook Air 13” Retina Display Late 2018 Battery Replacement and moving things over MacBook Air 13” Retina Display Late 2018 Upper Case Replacement I would personally not try moving the battery as remounting it will be difficult without the glue tabs.

The easiest way to do this would be stickers, laebls. or a keyboard cover. First, go to System Preferences>Keyboard>Input Sources and click the plus symbol at the bottom left. Select your desired language. Then put the keyboard cover, stickers, or labels on. You can change the keyboard layout by going to the top right corner by volume, clicking the flag, and choosing the desired keyboard layout.
