For a VC 2005 project, the Debug Information Format setting is found in the DebugInformationFormat="n" attribute of the .vcproj file, where n is:
0 = Disabled
1 = C7 Compatible (/Z7)
2 = Program Database (/Zi)
3 = Program Database for Edit and Continue (/ZI)
You could use the Replace in File action to update this setting.
