Harmony-like runtime patch system for Godot games

Hi,
I was wondering if there was already a way to apply runtime patches to methods in the same way that the Harmony 2 library enables for .NET games.
This library lets you define code that will run before/after a method that is already implemented in the application and you can access and modify the parameters and return value.
I know that the recommended way to mod Godot games is by using resource packs, but I don’t know if it is possible to modify ‘vanilla’ game behavior without overriding entire scripts (bad for compatibility between multiple mods).
I know that Godot officially support multiple programming languages, so I guess that this might not be possible depending on the way that game executables are compiled.
