Unable to cancel/delete the goals attached in performance document

We understand that goals associated with an active Performance Document can't be deleted based on standard functionality. However, we're looking for any possible workaround or recommended approach for situations where an employee has a large number of goals, including duplicates, attached to the Performance Document. This is causing the overall goal weighting to become extremely high (over 2000%), which is creating confusion and affecting the performance evaluation process.

Has anyone encountered a similar scenario, and is there a supported way to remove, exclude, reset, or otherwise manage these goals without impacting the Performance Document? Any guidance or best practices would be greatly appreciated. Thank you.
