User page use design options that can be found in the MyHome Theme > Property options > Category pages
You can customize there search form, hide some of the filters and more.
If you need more flexibility we recommend to create unique page for each user and redirect default link to the new page. The fastest way will be to install Simple 301 Redirects plugin: https://wordpress.org/plugins/simple-301-redirects/ . It allows to change any url that is part of your domain to the new location. 301 redirect is preferable for both users and search engines. We use it also on our own projects.
