We determine the supersymmetric AdS
7
backgrounds of seven-dimensional half-maximal gauged supergravities and show that they do not admit any deformations that preserve all 16 supercharges. We compare this result to the conformal manifold of the holographically dual (1, 0) superconformal field theories and show that accordingly its representation theory implies that no supersymmetric marginal operators exist.
