You'd have to do some fragile code to do this. Basically:

- get designer window from designer.view()'s parent window
- find the mActionAtlasPreview child action in the window
- manually toggle it on

This should work, but isn't stable API - so is likely to break ;)

A better approach is to (quickly, before 3.4 final!) file a PR
exposing the toggle atlas preview behavior to
QgsLayoutDesignerInterface. Then you'll be able to just do:

designer = iface.openLayoutDesigner( layout )
designer.toggleAtlasPreview( True )
