Completely hide/remove views exposed form?
If you're using hidden exposed filters instead of contextual filters, then you're already on a bit of a hacky path so you might as well just hide the filters with css.
If you think the contextual filters won't work which is sometimes the case, then the elegant solution is using the Global:Null contextual filter + Views Argument Substitutions to use parts of the url in the normal filters.
But really, just hide it with css.
