Constraint Details is a visual mode in studio, but is not an accessible setting found within Viewport Options. This is a bug and it should be found there.
Repro steps:
- Accidentally press the Alt+D hotkey combo that toggles Constraint Details. (Why is a hotkey conflicting with viewport movement keys?)
- Open Viewport Settings in the upper right corner of the viewport
Expected behavior
I expect the Constraint Details visualization setting to be found in Viewport Settings.
