DataScannerViewController - Updating Qualitylevel

I am buidling out a SwiftUI application which uses DataScannerViewController passed through a UIViewControllerRepresentable. WIth that said, I'd like to create a method to allow the user to change the quality level as they see fit however, every time I attempt to do so, the compiler tells me the below message which obviously means it's not mutable.

Cannot assign to property: qualityLevel is a let constant

Is there a known way to change this on the fly, or once the ViewController sets it - it's set and cannot be changed?
