Okay, no problem. In order to remove your site from the Ezoic platform, you'll first need to remove integration. You can do this under 'Settings' > 'Connection'. The next step will depend on your specific integration type.
Once you've removed integration, simply click on your domain name in the top right hand corner of the Ezoic Dashboard, then select 'Remove Site':Should you wish to re-add the site (or indeed any other sites) to your account in the future, just select the 'Add a Site' option from the Dashboard!
