Indeed. There is technically a Public Footpath there (Bressingham FP 35), as can be seen in the PRoW data that Norfolk County Council make available. See https://osm.mathmos.net/prow/progress/norfolk/south-norfolk/bressingham/ . However, I couldn't find any sign of it on the ground a few years ago either. For completeness the route is currently mapped as https://www.openstreetmap.org/way/372563171 . It might be worth reporting it to Norfolk County Council (perhaps via https://osm.fixmystreet.com/ ) as they have a duty to maintain the Public Rights of Way network.
