I see visible screws on the backside.

Is it possible to screw a belt clip there? And I don't mean in a case, but physically attached to the back of the phone with screws?

Some Chinese work phones have that feature, and it's stupidly addictive to be able to clip your phone anywhere!

The screws have a very easy direct access, I can see them being repurposed for other means with a bit of effort.
