I solved the issue with Ventoy. I created a bootable windows PE, then updated the bios file through windows PE.
Just in case someone needs it in the future. I used Hirens Windows PE iso with ventoy. I used two USBs, one for the bios file, the other for ventoy with the iso. Once I booted into windows, I clicked the bios file, confirmed I wanted to update, and then it updated. The laptop fans got scarily loud, but it worked fine otherwise.
