Newbie Requires help for Multiplayer Map Support for Dedicated Servers

Hello People,
I’m Tired of Single Player Game Making Now I wish to Develop a small Multiplayer Game where the game uses Dedicated Server. We know Dedicated Servers had no Visual, but How can i give Updates to players playing my game without touching unreal engine.

Short Brief : ME(Creator) —> Game Company ----> (Dedicated Servers provided by Game Company) -----> Game Company Needs to give Update like maps or character skins ----> But they don’t need to Call ME and asks for update
