A lot of the zenphone series had bootloader unlock as a listed feature which was then removed when they disabled and took down the tool. The Zenfone 10 was advertised as going to have the feature as well before and even after the launch for a bit. Asus claimed that the tool was coming at several points but the date in their promises kept getting pushed back and eventually turned into we don't know and now it appears to be never. This is stuff that was in writing from them, search it up, but you'll need to check the Internet archive for the info that they've removed from their own sites (like the repeated pushing and cancelling of the return of the unlock tool)
