Urgh, what a frickin' horrible feature to have in a config file, with no command line override. That said, it should be possible to fix via a regex tweak. There are several places where we call virStorageBackendRunProgRegex in storage_backend_logical.c. In all of those cases you need to tweak the 'regexes' definition to add a bit of magic to optionally detect and ignore the prefix.
