You cannot. Doing so is a violation of the Terms of use. If you wish to have a private wiki, then you will need to use a different wiki hosting service such as Miraheze or ShoutWiki. If you are not attached to the MediaWiki software, then there are also other options such as Wix, SquareSpace, and GoDaddy. A final alternative would be to host your own web server.
