In spring boot 3.2.7 it is possible, to modify the relation of an unexposed Entity with PATCH on the spring data rest controller for the parent Entity. Same PATCH request in 3.3.2 returns 2xx but does not change the relation.
In an entity-graph, with 3 entities and the "middle" one not being exposed by spring data rest, it is now not possible any more, to change the relation to another entity.
SchoolClass and Course are exposed via spring data rest, Pupil is not. We did not find a way to manage the relationship between Pupil and Course through the spring data rest endpoint for SchoolClass.
