I don't think an extra parameter is needed to achieve this, as this is something that the symbol vendor should already know about based on how it was constructed.
And after looking up the implementation, it seems this is already how it works right now: SymbolVendorELF (the only non-trivial implementation of this function) is only constructed if it manages to find debug info in an alternative symbol file (there's an `if (llvm::sys::fs::equivalent(candidate_file_spec.GetPath(), module_file_spec.GetPath()))` check in `Symbols::LocateExecutableSymbolFile`). If we fail to construct a SymbolVendorELF then a default SymbolVendor instance is created in `SymbolVendor::FindPlugin` (and that one has a no-op implementation of this function).
