What setting stops any travel across open holes/voids in a model?

Can anyone tell me what setting within Cura 4.12.0-BETA  stops any travel across open voids in a model no mater what size of holes.
In this image, the object is 30mm OD and ~18mm ID

    When cura keeps the nozzle within the print to get to a new spot, that's called "combing".  Versus a retraction move like shown above where it retracts the filament and moves directly to the new spot.  You want combing.


    Combing is a feature going back at least to version 15.x (from 2015).  It's currently under "combing mode".  You can set it to "all" or I recommend "not in skin".  


    In addition, check out "max combing distance with no retract".  I'm not sure but if you set this to for example 1mm, it may switch out of combing mode for those movements.  Although hopefully not.  But consider experimenting with this as well.  


    In addition note that those light blue lines inside your part are "retraction moves" and the darker blue moves (hidden as they are in internal layers) are non-retracting moves.


    It could be that you need to tweak your settings.  I usually can't see any stringing on most of my parts.  but it depends on a lot of things whether you get strings or not.
