Are there any restricted zones in gta online that are open in gta v story mode?

The only source provided discusses the game Manhunt and contains no information about GTA Online or GTA V. Consequently, we cannot confirm whether any restricted zones in GTA Online are available in the story mode of GTA V. If you need accurate details, consult official Rockstar Games documentation or community guides that specifically address GTA Online and GTA V gameplay differences. Until such evidence is provided, we must state that the question remains unanswered.
