Because there is a difference in hardware between Mi 8 and Mi 8 EE (classic fingerprint reader vs fingerprint under display). Not sure for 100%, but it should work for Mi 9 TE.
I was running on 10.2.5 Global EEA for a 7 days and after unlocked BL. Now I'm on lastest weekly and this ROM is much more faster, everything so smoooth, but Goolgle Pay is not working at the moment.
