Set up a udp echo server at the host you want to ping.
There are many ways of doing this, my favourite way is:
socat -v UDP-LISTEN:4000,fork PIPE
Now a echo server is listening at port 4000.
If you dont have socat, use apt install socat or yum install socat, you will get it.
Ping you server.
Assume 44.55.66.77 is the IP of your server.
./udpping.py 44.55.66.77 4000
Done!
Now UDPping will generate outputs as a normal ping, but the protocol used is UDP instead of ICMP.
