How can I enable 120 Hz output on HD 620?

I am using an i5-7200U Surface Laptop, which drives a 1920×1080 monitor, set at 120 Hz. The HD 620 is only managing to output 60 Hz (up to 70 when using EDID overrides). This is a significant downgrade from the 120 Hz that was being output by the HD 4400 present in my much older Surface Pro 2, using the same cable and monitor. Is there a driver patch coming to Kaby Lake mobile graphics, or is there another workaround possible?
