These three options are the only options available. The three options you will be given in step 2C of your steps are:

1. No, do not display the email opt-in checkbox. Opt-out constituents automatically.
2. No, do not display the email opt-in checkbox. Opt-in constituents automatically.
3. Yes, display the email opt-in checkbox. Luminate will also give you the option to display the checkbox, and for the checkbox to be checked by default.

We do not have an option to both hide the check box and neither opt them in or out. In most cases the recommended option is to select number 3, and to select the option for the checkbox to be checked by default. This will give your constituents the opportunity to choose the way your organization will communicate with them.
