Persistent object caching is not enabled

I’m using Comet Cache Pro, and when checking Site Health in WordPress, there’s an error that reads:

Persistent object caching is not enabled (for AMP)

I understand that’s for database caching. Is there an option in Comet Cache that could enable it? If no, I was thinking of using Redis Object Chace plugin. Would that interfere with Comet Cache in any way?

Thanks in advance.
