Describe your suggestion

There should be a setting (you can toggle on/off) that when you done building than baritone log out of the server/world (disconnect/save and quit to title)

Settings

Toggling logout when done building using #sel, or #build

Context

When you want to build something big overnight and afk, I want that server is not loading all the time, So i can diconnect when done building

Final checklist

• I have not used any OwO's or UwU's in this issue.

doesn't #disconnectOnArrival do that?

No, disconnectOnArrival is for walking / flying to a specified coordinate (#goto, #elytra and related commands) and if it interacts with #build then that is a bug and probably not useful.
