The cook top has Unit switch (es), and the breaker at the panel.

I'd say technically you do not, if the unit switch disconnects all ungrounded conductors to the cooktop. For a single family dwelling, the service disconnect can even be the other disconnecting means.
Homework answer: no.
Field answer: yes, because I don't want a discussion about it.
