How can I set the Referrer Policy value

[derun]

Since chrome version 85, the default value of Referrer Policy is strict-origin-when-cross-origin, but the chrome version of QWebEngineView (qt5.14.1) is 77, and the default value of Referrer Policy is no-referrer-when-downgrade. How can I set the Referrer Policy value to trict-origin-when-cross-origin when the Qt version is not upgraded, does anyone know?
