Chapter 3 of UEFI 2.4 defines the variables that control boot policy.
Section 7.2 defines how the variable services work, to discover, read, and
write the variables.
How to access the variable services from WinPE I have no clue, but that seems
like something to ask on a WinPE forum. You need access to the EFI Variable
Runtime Services.
