It's highly unlikely that you would be the target of such a highly sophisticated attack, but a hacker could get into a place where you left your computer without surveillance (such as your home or a hotel) for about 15 minutes, and install it inside your computer.

If you think you could be the target of such an attack, you could maybe enable an alert in the settings of your UEFI if your computer has been opened (I know that my ThinkPad has that option), or the better option is to always keep your laptop with you.
