First of all, this is not true. Anybody can install a distro like Linux Mint or Ubuntu, it doesn't require any tech knowledge. Many Linux distros are perfectly fine for the average user. Second, requiring complicated BIOS changes constitutes an artificial hurdle for any Linux distro to be easily installed by an average user. So even if you were right, the measure would also ensure that future versions of Linux that are decidedly more beginner-friendly would be prevented from being installed, creating an artificial, anti-competitive barrier.
In a nutshell, this is bad no matter how you look at it.

What you think as "not tech knowledge" is a serious skill that is severely lacking in billions of people.
The user needs the install medium, they need to get it, download it, create it, get a USB or blank CD/DVD, etc. They need to either have the courage (or curiosity or aloofness or determination) to modify their computer on such a drastic level, they need to understand abstract concepts, follow a written manual that uses those concepts, they need to recognize those abstract concepts as they are implemented on the computer they are currently tinkering with, and so on, and so on.

True, but it's bad because the whole "personal computing" thing is bad. This detail is largely irrelevant.
