problem wp-json / contact-form-7 / v1 / contact-forms / 12 / feedback / schema

I have a problem with the contact form plugin, when I analyze the site with gtmatrix it reports me slowness due to the wp-json / contact-form-7 / v1 / contact-forms / 12 / feedback / schema, I ask you how I can avoid this, I lose over 2 seconds, thanks.
