[REQUEST] Lenovo Thinkpad 10 Tablet 32-bit to 64-bit

[KineticWing]

Hi there. Long time programmer with very little BIOS experience looking for help. Hope I'm posting this in the right place.

I have a Lenovo Thinkpad 10 that I would like to move from 32-bit Windows to 64-bit Windows. The processor is compatible; however I've run into the problem that I have a 32-bit UEFI, and the manufacturer does not have a 64-bit update available.

The frustrating thing is that there is an identical-in-every-way-except-for-the-RAM version of the tablet for which they DO have a 64-bit version available. There is a toggle at the top of the page where you can simply select your current operating system. Check it out here: https://pcsupport.lenovo.com/jp/en/produ.../downloads

Running the 64-bit installer is futile at this juncture; it gives a "directory not found" error. Is there any kind of modification that can be made to enable the installation of the 64-bit UEFI so that I can subsequently run a clean install for 64-bit Windows?

Thank you in advance!
