Alternate to no-cost developer subscription - enabling repos

Hi.

I'm currently having registered no-cost developer subscription via which I enable below repos:

$ sudo subscription-manager repos --enable rhel-7-server-devtools-rpms $ sudo subscription-manager repos --enable rhel-7-server-extras-rpms

$ sudo subscription-manager repos --enable rhel-7-server-optional-rpms $ sudo subscription-manager repos --enable rhel-server-rhscl-7-rpms

My question is, is there an alternate way of enabling these repos if one don't have registered subscription?

Thanks
Hasan
