Deploy new website under development in a hidden url

We are working on teh new OTS website, some people would like to give feedbacks or work on the design without the need to install on their own computer.
Is possible to deploy the website on an different directory?

I don’t know how is our current deployment process nor the server, can someone taht worked on current website help me on this?
