You don't indicate what insurance you wish to be removed from; if it is health insurance, you have a right to decline it (but remember: if you do, you will not be able to be reinstated until next open enrollment, unless certain qualifying life events occur); if you employer will not let you do this, contact the insurer or insurance adminstrator directly, explain the situation, and ask them to help out. Do this before the open enrollment period ends, since once it ends, you are locked into whatever your status had been.If you are talking about another employer-provided benefit, like life insurance, if you have to pay for it, you typically have the right to decline it, but  if you don't pay anything and it's just given to you, you might not be able to--it would simply be something that comes with your job, like sick or vacation days.If you have an employment contract (which would be unusual; most people don't, unless they are in a union), however, you need to look at what the contract says--the terms of the contract will affect or control what you can do vis-a-vis insurance.
