Lenovo laptops silently stripped of important feature in BIOS updates

Various users of Lenovo's Legion laptops have been complaining about a missing feature on their laptops on Lenovo's forums since April of 2021. This missing feature is the H.264 encoding codec, an encoder that the NVIDIA graphics card in these laptops use for Shadowplay. This codec is also used for hardware-accelerated video encoding in software that supports NVENC, some of which isn't strictly for content creation.
