How to install 64bit BIOS after installing 32 bit

Originally I received the board with the 64 -bit BIOS package and the device would automatically boot into the built-in EFI Shell. I ended up wanting to try Windows IoT Core, so I installed the 32-bit BIOS using the shell commands found: https://up-community.org/downloads/uefi-bios
Now it seems I am stuck on the 32-bit BIOS because I am unable to get the device to boot into the built-in EFI Shell.
Does anyone have any ideas of how I can get back to the 64-bit BIOS?
Thank you,
Zach

You can disable on board eMMC by below BIOS Setup setting,
'Chipset'->'South Bridge'->'SCC eMMc Support' -> 'Disabled' -> Save & Exit.
See if this works.
Any other ideas of how I can get to the shell window to switch BIOS?
The latest BIOS version remove the EFI shell application to include additional features like the PXE Boot.
We will provide soon a re-packaged version of the BIOS installer archive which will include the EFI shell outside of the BIOS binary.
This will allow you to boot into a shell where to run the BIOS update command.
The package will be available later this week.

Or at least give us a more thorough procedure.
"Put files from BIOS package into UEFI bootable USB drive" was a little too vague for me.
I figured it out eventually but it took a lot of trial and error.

After that unpack up-community.org/downloads/uefi-bios/uefi-bios-upc1bm0x archive directly to the USB root dir:
important! there should be /EFI/BOOT dir with bootia32.efi module from the archive
I recommend to delete outdated and poorly written /EFI/BOOT/startup.nsh script - it calls reset w/o any delays that confusing first time.
After you successfully boot in EFI shell go to fs1: disk and call go_32_64.nsh script to update BIOS.
