No; while we do indeed have an option of updating policies published via the Policy module and accessed via Policies in Progress, when it comes to a Policy that has been included as part of a Fusion course, then updating the policy in this instance is not currently possible. (Likewise, you cannot edit a Fusion course, once published.)

• If you have an updated version of the Policy that you need to include in the course, the best way to do so would be to Archive your Published Course, Create a Copy of your Fusion Template, and make the change to your Policy at this point before retargeting to your users.
• Your users will receive a new notification to complete this course at the point of publishing, and will be able to review the new Policy within.
• The Archived course (with the original policy) will no longer be accessible to ensure your users have no access to an outdated policy.
