No, that will not achieve that effect. That would mean that the object
is not shaded. That's not the same as not casting shadows on itself.
A sphere can't cast shadows on itself but a torus can (due to their
form).

: specifying 'double_illuminate', depending on the specific effect you want.
I think that double_illuminate will not eliminate any shadow calculations.
