Is it possible to re-lock the bootloader after I installed MIUI EU ROM on my Redmi Note 11? I’ve never done relocking bootloader on custom ROMs, and this thought pops on my mind when I realized my banking app don’t work with unlocked bootloader.
Thanks.

Tl,dr: Yes it is, but your ROM and recovery must be signed.
