USB-C HDMI no longer working after BIOS update

[The_Rickstar]

I can no longer use HDMI over USB-C after my last bios update. My computer is Lenovo L340-I5IRH. I think this is available through the advanced pages of the BIOS but I cannot be certain. I don't know how to get my bios dump unfortunately. So I cannot provide it here. Can anyone help me access the advanced(hidden) pages of the most recent bios? Most recent bios is here:https://support.lenovo.com/us/en/downloads/ds539787-bios-update-for-windows-10-64-bit-l340-15irh-gaming-l340-17irh-gaming

Thank you for your help!
