Yes

Chris is correct, humility is a modifying effect that is always active, so a creature with an ETB ability will enter already modified before state-actions are checked. By the time any ETB triggers would be put onto the stack, it would have lost all abilities, leaving no triggered ability to trigger for ETB.
