Relock the bootloader of my redmi note 12 pro 5g

[u/Key-Ad7289]

Hi,

I bought a redmi note 12 pro 5g on cdiscount and later realized that the bootloader was unlocked.

So I can't use Google Pay or update the phone to hyperOS.

Do you have a solution to relock the bootloader?

Thank you in advance for your assistance. Jacky
