Hi Richard.
Installing the latest forge application as a separate application is not possible as far as I know. What is possible (but a bit more work) is what I did with another component in a similar situation. I cloned that component and changed all references to the cloned component and deployed those changes to prod. Then I install the latest version and changed the references again to the new version.
A bit more work but is safe to do.
Greetings,
Vincent
