Overly aggressive security with larger Contact Form 7 forms

We have a website with a survey form with ~50+ fields. The form was created using Contact Form 7 and Contact Form 7 Conditional Fields.

Recently we started experiencing issues where the form was not submitting. We’ve tested around a bit and this is what we’re seeing under Cerber’s activity monitor:

Malicious request denied Suspicious number of nested values
URL: [domain name]/wp-json/contact-form-7/v1/contact-forms/2574/feedback

We’re using the version 7.6 of Cerber and we’ve ensured that Contact Form 7 is an allowed/not-blocked REST API endpoint.

Any ideas on what’s happening here?
Can we moderate Cerber’s behavior to be less aggressive at blocking certain form submissions?

As for now, we’ve had to disable Cerber to allow this survey form to be used which is not ideal.
