How to add go-gorm tag in .proto file?

I define a test.proto:

message PlayerRegister {
    string GameSvrId = 1;
}

Then generate a test.pb.go:

type PlayerRegister struct {
    state         protoimpl.MessageState
    sizeCache     protoimpl.SizeCache
    unknownFields protoimpl.UnknownFields

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

In this case, when I use Gorm, the SQL is:

INSERT INTO `player_registers` (`game_svr_id`) VALUES ('1.0.0')

But I want the SQL is:

INSERT INTO `PlayerRegister` (`GameSvrId`) VALUES ('1.0.0')

I want table and field names are the same as defined in the test.proto, I know can add gorm:"column:GameSvrId" in struct, but how code in proto?

What should I do?
