How to manaully open cpative portal login page with https url without hsts error?

I an a network engineer, I have a question about safari captive portal https redirect.

I try to manually enter a https url at both safari and Chrome when connect with captive protal network, but only Chrome pop up the captive portal login page and safari just show "safari can't establish a secure connection to the server" because of hsts.

I search from the Internet, it says that when behind a captive portal and client try to access https url, Chrome will access "http://www.gstatic.com/generate_204". This behavior will lead to pop up captive portal login page.

I hope to reach the same result in safari. Safari has any solution to handle this situation?
