In ${\cal N}=5, 6, 8$ supergravities there are hidden symmetries of equationsof motion, described by duality groups $SU(1,5), \, SO^*(12), \, E_{7(7)}$respectively. UV divergences and known candidate counterterms violate thedeformed duality symmetry current conservation. Extra higher derivative termsin the action are required to restore duality. We study the effect of atwo-vector part of the counterterm for ${\cal N}\geq 5$ supergravities usingthe universality of the symplectic structure of extended supergravities. Weconstruct a compact form of a deformed action with infinite number of higherderivative terms and restored duality symmetry with deformation parameter$\lambda$. We find, in $\lambda^2$ approximation, that the $SU({\cal N})$symmetry of the deformed theory is restored on shell.
