@wtrocki @rkpattnaik780 I am relatively new to OSS and would like to give this issue a shot. Let me know how I can onboard myself with this and where I can look for the code to change

Thanks @amoghrajesh ! You would need to make changes to the file pkg/cmd/registry/list/list.go.
You can have a look at how topic list validates the flags.
