Thank you for reaching out! I’m afraid that the plugin does not currently have this option. Categories can only be disabled individually.
As much as I’d love to help you with this one, I have to admit that I cannot. I’m really sorry.
Even so, I have added this feature on our development log, however, I can’t say if or when it will be added to the plugin. This is the first request we’ve had for this.
Thank you and best wishes,
