How Can I uninstall the SAM products?

Check out this article which takes you step-by-step through uninstalling SAM on version 2020.2.6 or earlier. If your version is later than 2020.2.6, I suggest you contact support to make sure the process is the same.

Any additional questions, you should probably reach out to support so they can understand your specific environment and make the appropriate recommendations. 

In the command line, run the following command:

'path to exe'\SolarWinds.Orion.Installer.exe -uninstall

---I Tried to run above command to uninstall all the components, but it's not working.

I'm sorry I missed your reply. Since this is the SCP forum, I don't watch it as closely as I do the Classroom forum. I agree that if you are having issues, please raise a support ticket. Ease of uninstall is something that the product team has continued to work on and improve. That's not to say that there isn't an issue sometimes, particularly from influences in the environment. I hope support was able to assist you!
