Service decorator for entity list builder?

Is it possible to use a service decorator, or similar mechanism, to override a method in an entity’s list builder?

For my specific use case, I want to override the render() method of the Drupal\webform\WebformSubmisionListBuilder class, which is the list builder for the Drupal\webform\Entity\WebformSubmission entity. I’d prefer to not have to replace the list builder class entirely.

I did come across this post, but it doesn’t seem to provide a solution to my use case. I also didn’t fully comprehend the information in the post, so I might have missed the solution.
