You can script a change to that registry entry via the Cygwin regtool script. You can do this in an install or post-install script or upon each invocation of your application, providing it's invoked via a script. The man page for regtool includes sufficient detail to enable you to incorporate this sort of functionality in your software. I recommend that you consider carefully the logic you use to alter the "heap_chunk_in_mb" key so that you don't undermine an existing customization already applied by your end user.
