Correct. Its locked down so that it cant be tampered with. Friends, family, thieves, police, three letter government agencies, and even Apple are unable to tamper with it once the user has set up the phone. It is designed to protect your data from anyone else but yourself.
You want to take away that feature from me because you want to load another OS on it? Just go buy a Pixel phone and flash GrapheneOS on it.
There are sooooo many devices out there that do not have any way to unlock bootloaders. Why are you focusing so much on Apple and their secure bootloader?
They absolutely use modern UEFI on their Intel-based Macs

Yes now do iPhone.
I can’t think of ANY phone that uses UEFI. Most phones are using ARM processors, and use a different method of booting vs x86 devices.
Which ARM UEFI bootloader do you want iPhone to use?
Yes, the whole subject is about how terrible phones are. Apple can write UEFI firmware but they like control.
