–rewritesenable is a parameter to the CommandBox command and has no bearing on IIS.
In IIS, you must configure rewrites separately. Please see our docs here:

You seemed to mention a dislike of rewrites earlier. They are optional, but they are also the only way you can remove the “index.cfm” from your URLS.
Thanks!
