Hi, Tamilselvan Sivasankar
Welcome to the Microsoft Community.
Uninstalling Edge via command doesn't work anymore, so I can't provide you with a valid command, and Edge being an important component of Windows, it's not recommended that you try to uninstall it.
Can I ask if you are having any problems updating? Is it possible to provide the error code so that I can analyze your problem?
I am looking forward to receiving your reply.
Best Regards
