Create site collection or web application for my site in SharePoint 2016

I have installed SharePoint 2016 in multi server farm with MinRole architecture and with it the User Profile service Application got Automatically configured. The service application has default My Site Host URL as http://spwfe03p-bro:80/my/ :-

Now my question is that how to create new Web Application or Site Collection as: http://spwfe03p-bro:80/my/ . I am asking this because if I directly create new site collection under http://spwfe03p-bro:80. It will be something like: http://spwfe03p-bro/sites/my and not http://spwfe03p-bro:80/my/

Any idea how to achieve this?
