No, you can't.
The original passage states that modern and avant garde sculptors generally were not commissioned to produce war memorials, it does not state why.
They are contrasted with figurative sculptors, who at the time of the war were often (and sometimes still are) assumed to be more socially and politically conventional, hence the use of 'even' to introduce the surprising(?) fact that their commissioned works were somehow anti-war, and hence unpopular. Artists generally have idiosyncratic or no political views, the implied dichotomy is a bit naïve. Surely anybody with eyes and a brain would consider the First World War as the greatest (by then) act of collective human folly? What competent and responsible artist would conceal that after the war?
Note that in describing styles of sculpture, 'figurative' means the same as 'representational' in painting, i.e. it describes sculpture which attempts to portray physical reality. Michaelangelo's David is figurative, Barbara Hepworth's work is abstract. The relationship between classical/modern and figurative/abstract is not simple: Rodin's work was modern but also rigorously figurative.
