Preprocessing directives to avoid code containing addressables until package is installed?

I was wondering if there are preprocessing directives I could use or some other way of avoiding scripting errors related to the addressables package not being installed?
In editor mode, I kind of want to make a tool that I can bring into a project and use to tell addressables to install and then tell it to create the exact initial addressables group configuration I'll be needing.
But of course the script that creates the initial group configuration needs addressables as a dependency, so it creates a compiler error if the package is not yet installed.
So I can't also have a script that installs the package because the error in the other script will cause all the scripts not to run in the editor.
So basically, I want to make unity skip compiling my group configuration script until the addressables package finishes installing.

 

make your tool a package, then add

com.unity.addressables

to its dependencies.
