That is correct. Samsung OneUI 8 removed the ability to unlock the bootloader to any device that installed it. It removed the toggle and also removed the functionality from the codebase as well.
I got screwed by this by buying a used Samsung Tablet for the purpose of rooting it and made the mistake of letting it update after I factory reset it. Never buying a Samsung product again.
