Well, in theory there is no deliberate allowance for camber adjustment in the design, but due to all these cars based on this platform (Skoda Fabia) being designed for "low tech" assembly or re-assembly, the fixing points all have over sized holes so there is some adjustment possible.
You are spot on as regards lowering the ride will affect the camber, I seem to remember that there is an adjustable TCA rear bush - but other than that it would be down to moving the top mount out a bit - might be a kit for that as well.
