Is there any environment variable that can be checked here instead of 
using extended?
If we can somehow know that this is a CI execution with some environment 
variable we can use that instead.
It will allow executing test without extended flag.

If we don't have any such env variable I am ok with this approach just 
add a info message to notify
user we are shortening the list also add a intel platform check.


Thanks and Regards Kunal Joshi
