How to remove the safe mode of my laptop

There is no way to really remove it, but you can make it difficult to access. But first, why would you want to do that? Safe mode is a very important tool to repair Windows, and removing/disabling it can cause you to loose everything if Windows no longer boots normally.

But, if you are "stuck" in safe mode, when you boot, and cannot boot
normally, that is a different issue.
