Unable To Update BIOS

I’m trying to update the BIOS for my Framework laptop. It was originally dual-booting Windows and Linux Mint, but I have removed Linux from the hard drive completely, so it is currently a Windows only machine. When I try to run the updater, I get the following message:
“The BIOS image to be updated is invalid for Secure Flash or onboard BIOS does not support Secure Flash”
I’ve seen others with this issue, but they seem to all be using Linux partitions. Anyone have ideas on what to do?

You probably still have remaining Linux data on the drive.

Is secure boot enabled?

Currently enabled and it didn’t work. I had it off earlier but it didn’t work either
