Any way to disable globalTypes generation?

I'm trying to use codegen in an existing codebase and can't run it on all files as that fails due to numerous issues (imported fragments from other modules, anonymous operations, etc)

What I've instead been doing is running codegen on new code. It works but whenever globalTypes is generated it overwrites previous data – this leaves older operation types without enums

Is there a way to disable globalTypes generation and keep enums local?

Start at the codegen entry point that produces globalTypes and reproduce generation on separate batches of operations, including imported fragments and anonymous operations. Done means an option can disable globalTypes generation while enums remain local and previously generated operation types are not overwritten.
