Not in the standard scaffolding, no. The new layout is trying to lean hard into the new Turbo tooling, and uses Turbo Frames to manage the layout of the various partials. Since you can’t put anything inside a TBODY that isn’t a TR, and a turbo frame is a custom element that isn’t a TR, this scheme would not work. Instead of figuring out a solution to that problem, they punted and used a nasty stack of DIVs in the index view.
