The only option you have atm to avoid that is to turn off "Always deploy project before running it" in "Options > Projects > General". Please note that Qt Creator then will *never* deploy your application when you press the run button, even if there were changes. You'll then have to run the deploy step manually (by choosing "Build > Deploy" or assigning a keyboard shortcut to that menu).

(Qt Creator master (which will be released as 2.5 at some point) adds a "Run without Deploying" action, which then can be used instead).
