Prevent submitter from voting

Hi,

Pretty new to Web Help Desk so forgive me.  We are currently running 12.3.0 if that becomes relevant.

I'll give an example scenario below:

CAB approvers = Person A, Person B, Person C

Minimum approvers = 1

If Person A submits a ticket that requires this approval process, is it possible to prevent them from voting on their own ticket to get it approved?
