ClayXv I'm afraid I don't understand enough of what you're trying to accomplish to give a helpful response.
Official instructions are to install Flarum in its own directly, then update the DocumentRoot/WebRoot in the host settings ("public directory" solution, like Laravel and other modern apps use).
If that doesn't work, the second solution is to use the "Customizing Paths" instructions to transform Flarum into a more traditional "shared hosting" structure, which can be dropped in a non-customizable DocumentRoot.
Once you followed "Customizing Paths", you can move the Flarum folder wherever you want just like if it was any other typical PHP app.
