By default, Leadcamp tracks all forms on your website if the tracking snippet is installed and your website visitors have cookies enabled.
To disable certain forms that you do not want to track, you must disable page tracking.
Go to the menu > Workspace settings > Tracking
Scroll down to Identified referrers
Find the page you want to disable
Hit the 3 dots next to it
Click Disable referer

This will now disable the tracker for that particular page and thus disable form capture.
