DISABLING 3 WAY HANDSHAKE - ns-3

Question

I am not able to figure out anyway on how to disbale 3 way hanshake in ns3
I am using NetAnim to trace the packets of the Below code
#include <fstream>
#include "ns3/core-module.h"
#include "ns3/internet-module.h"
#include "ns3/sixlowpan-module.h"
#include "ns3/lr-wpan-module.h"
#include "ns3/internet-apps-module.h"
#include "ns3/mobility-module.h"
#include "ns3/netanim-module.h"
using namespace ns3;
using namespace std;
NS_LOG_COMPONENT_DEFINE ("Ping6WsnExample");
int
main (int argc, char **argv)
{
bool verbose = false;
CommandLine cmd (__FILE__);
cmd.AddValue ("verbose", "turn on log components", verbose);
cmd.Parse (argc, argv);
cout << "verbose : " << verbose << endl;
LogComponentEnable ("Ping6WsnExample", LOG_LEVEL_INFO);
NS_LOG_INFO ("Create nodes.");
NodeContainer nodes;
int n = 3;
nodes.Create (n);
SeedManager::SetSeed (167);
// Install mobility
MobilityHelper mobility;
mobility.SetMobilityModel ("ns3::ConstantPositionMobilityModel");
Ptr<ListPositionAllocator> nodesPositionAlloc = CreateObject<ListPositionAllocator> ();
for (int i = 0; i < n; i++)
nodesPositionAlloc->Add (Vector (0.0 + i * 5, 0.0, 0.0));
mobility.SetPositionAllocator (nodesPositionAlloc);
mobility.Install (nodes);
NS_LOG_INFO ("Create channels.");
LrWpanHelper lrWpanHelper;
// Add and install the LrWpanNetDevice for each node
// lrWpanHelper.EnableLogComponents();
NetDeviceContainer devContainer = lrWpanHelper.Install (nodes);
lrWpanHelper.AssociateToPan (devContainer, 10);
cout << "Created " << devContainer.GetN () << " devices" << endl;
cout << "There are " << nodes.GetN () << " nodes" << endl;
/* Install IPv4/IPv6 stack */
NS_LOG_INFO ("Install Internet stack.");
InternetStackHelper internetv6;
internetv6.SetIpv4StackInstall (false);
internetv6.Install (nodes);
// Install 6LowPan layer
NS_LOG_INFO ("Install 6LoWPAN.");
SixLowPanHelper sixlowpan;
NetDeviceContainer six1 = sixlowpan.Install (devContainer);
NS_LOG_INFO ("Assign addresses.");
Ipv6AddressHelper ipv6;
ipv6.SetBase (Ipv6Address ("2001:1::"), Ipv6Prefix (64));
Ipv6InterfaceContainer i = ipv6.Assign (six1);
NS_LOG_INFO ("Run Simulation.");
AnimationInterface anim ("animation.xml");
Simulator::Run ();
Simulator::Destroy ();
NS_LOG_INFO ("Done.");
}
I don't want the packets of 3 way handshake to be visualised in NetAnim (to differentiate other packets and handshaking packets)
So what should I do to differentiate them ?
Note : I am new to ns3 so tips on using NS3 is more appreciable
