Is it possible to set something in the innosetup script files to make the final "restart to complete installation" screen default to no, instead of yes?

I have to test out my builds often several times a day, and typically do so by just hitting enter on the installer until it's finished, since it remembers all settings. But once in a while some file will be locked, and since we use restartreplace for everything, it'll start rebooting before I can catch it. Stress level nicely skyrockets when that happens. I know some of our users are like that too, so is there any way to make no the default action?

Thanks for any help!
