If you're asking whether they own the Fox cartoon, yes they do. They acquired it when they bought Saban Entertainment in 2001. But it hasn't seen the light of day outside Europe since then since Disney likely doesn't want it to cause "brand confusion" with their version of Peter Pan. So even if their library of non-Marvel Fox Kids cartoons do end up on Disney+, Peter Pan and the Pirates probably never will.
