General Questions • [Software] Update a legacy BIOS boot to use UEFI?

I have an old Lenovo Thinkpad (1st gen x1 carbon) that I've been running Debian on for quite some time (since Squeeze). When I initially installed, UEFI was still relatively new (at least in production) so I just disabled it and installed Grub with "legacy BIOS only".

As per that other thread, I'm having some issues with Bookworm. In my travels I've noticed that there are firmware updates available. But I've removed Windows and 'fwupd' refuses to work with legacy BIOS, so it looks like I need to re-enable UEFI boot. However, when I do that, my system doesn't boot. So I'm guessing that I need to make some changes. Poking around I see there are specific grub packages, but it also seems that I need an additional UEFI partition.

Can anybody help me with the specifics of what I need to do? I don't need hand holding, but I do need at least a high level overview of the steps required.
