Follow these steps to stop the automatic sharing of your feed content: 

1. Log into the BrandConnected panel 

2. Click Content & Feed > Manage feeds  

3. Under the 'Manage Feeds' section, you'll see all the feeds added by you. Navigate to the feed you want to edit and change the Auto-Sharing from 'Active' to 'Inactive'. 

Now, your feed content will no longer be shared automatically from your accounts. You can still share it manually from the  'Schedule Feed Content' tab.
