A simple thing to make evil maids job harder is to just apply plenty of instant glue. This way it takes much more effort to open the laptop or switch components. Also fill in ports you don’t need. For practical security it is also important to have some physical things on the laptop body that allow you to identify your hardware. Otherwise somebody will just replace it with their own hardware to collect your password. Obviously pretty much anything can be replicated, but absolute security is anyways impossible to achieve so you can only try to make things harder for them.
