You user is always free to lower down UAC protection. For example, on Windows 7:
Control Panel -> Small Icons (All Control Panel Items) -> Action Center -> Change User Account Control Settings.
If your customer lowers the slider down to "Never Notify", she/he won't have UAC messages at all. It's important that they make this questionable decision by themselves and that you won't do it on your computer. :-)
And of course, your application cannot lower down UAC, otherwise it would defeat the purpose of the whole idea of UAC.
You can do different thing. You may know that your application would always need elevation of privileges. In this case, you may want to request elevation of the privileges in the very beginning, without having the user to use "Run as Administrator" or using equivalent *.LNK. This is done by claiming requested permissions accordingly in the embedded application manifest. Such manifest is created and embeded very easily. Please see:
