Is there a way to trigger AVform validation only on submit ?

[JagadishLakhini]

I want to validate all avfields ie. complete avform only on submit instead of Onchange or OnInput. In Module, there is a prop named 'validationEvent' which has default value as ['onChange', 'onInput']. Tried to override using validationEvent={[]}, it doesn't work as well. Is there any other solution to resolve this issue ?
