How to avoid go vet copylocks warnings?

e.g.

// goverter:converter
type Converter interface {
    Convert(source []Input) []Output
}

// generated gRPC code
type Input struct {
    state         protoimpl.MessageState
    sizeCache     protoimpl.SizeCache
    unknownFields protoimpl.UnknownFields

    Name string `protobuf:"bytes,1,opt,name=name,proto3" json:"name,omitempty"`
}

type Output struct {
    Name string
}

goverter -ignoreUnexportedFields ./example/simple

generated.go

call of ***** copies lock value: ***** contains google.golang.org/protobuf/internal/impl.MessageState contains sync.Mutex

I want to use pointer.
