Change or hide portal URL

Hello,

I have vra version 7.0.1. I dont want user to see real URL ( https://vraapps01.domain.local/vcac/bla bla ) when they login the portal. I tried to use HTML IFRAME but i could not show web page inside IFRAME. I think user should see same url when they click anywhere ( https://cloud.x.com ).

Is there an easy way to do this?

Thanks.
