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.
Your banking app can only tell wether or not your bootloader is unlocked as far as your rom is telling it. I suggest finding magisk/Xposed modules to make it stop thinking it is unlocked, similar to how one may fix gpay.

Tl,dr: Yes it is, but your ROM and recovery must be signed.
I tried these commands before, and I encountered red flashes and my phone was unusable. I went back to original ROM.
No. While it is in theory possible if you sign the image, it’s not worth the risk. If you relock the bootloader on a Xiaomi device and the image isn’t signed (and it most likely wont be) the phone is done for. Relocking gives basically no advantages that can’t be fixed through a root module.
One exception I have seen so far are the UBS banking apps - even with tools like LSposed, HideMyApplist, and Shamiko, the UBS apps still refuse to run. Other banking apps / other apps I use don’t have this stubbornness.
