FW13 Intel 12th Gen 3.08 BIOS update - Does it fix the 1st Gen HDMI card battery drain issue?

After it was announced, I upgraded my Framework 13 (Intel 12th Gen) to the latest 3.08 BIOS update. In the release notes, it mentions:

Fixes:

8. Reduce power consumption when DisplayPort/HDMI Expansion cards are used

I have a 1st Gen HDMI expansion card, for which there exists a hardware fix for its battery drain issues. Does the 3.08 fully resolve the power draw issues, or would I still need to perform the hardware fix?
