Do Anti-Phishing Advanced Thresholds Affect Anti-Spam Detections in MDO?

Currently I am facing a predicament with a high volume of emails being flagged as high-confidence phishing under the "Advanced filter" detection technology by our anti-spam policy, a vast majority of which appear to be benign. I have noted the "Advanced phishing threshold" in the anti-phishing policy, which is described as "These thresholds control the sensitivity for applying machine learning models to messages to determine a phishing verdict"

I have not, however, found any concrete evidence that these 2 settings in completely different policies are in any way related. Is there any way to tune the thresholds for the "Advanced filter" detection technology?

    If they are flagged as high confidence phishing, the only real option is to submit these to Microsoft as false positives:
