It's not hidden, it's shown in disk management, it's just not mounted by default.

IMO that is perfectly reasonable considering 99.999% of users will never want or need to do anything with it and those who do want/need to access it should have no problem finding a single well-documented command. For everyone else it's just a "delete system32" level temptation to do something stupid that'll break their system.

mountvol <letter>: /s

I honestly have no idea what it'll do if multiple EFI system partitions are present though. I presume this command will mount the one Windows has booted from.

Yeah, but even then to change the default loader you'll need to point it to something else using some arcane bcdedit command. Dropping some PE binaries is not good enough.

Or just boot in to the EFI config interface and set a new default that way.

Only if it's registered! Registering a new binary isn't usually in the customer motherboard menus.
