The settings can be found in the Profile Editor (Preferences > Java > Code Style > Formatter > Edit...) under the Line Wrapping > Wrapping settings > Binary expressions subsection.

It's only possible for right-sided nesting.
Find the Chained conditionals setting in the Profile Editor under the Line Wrapping > Wrapping settings > Other expressions subsection.
