Yes, there are a few ways to track history for a long text area field:
Custom objects and fields: Create a custom object with fields to store previous versions of the long text area field and track changes over time.
Salesforce Chatter: Use Salesforce Chatter to track changes to the long text area field. You can enable Chatter feed tracking on the field and track updates and changes made to the field in the Chatter feed.
Custom history tracking: Write custom code to track the changes made to the long text area field and store the information in a custom object or in the record's field history.
