It is possible to customize it, but it's not very documented. Afaik you only have APIs for setting its color and so on. If you want to do further customization, you'll need to re-implement that part yourself.

The code for the built-in tracking can be found here: http://zbar.hg.sourceforge.net/hgweb/zbar/zbar/file/443c9f0e3c8f/iphone

This will disable the autofocus property in zbar sdk reader.tracksSymbols=FALSE;
