Sony Xperia XZ2 - lock bootloader

How can I lock bootloader in Sony Xperia XZ2?
I wanted to update to Android 12 as internet banking app does not support Android 10 anymore - the last version officially provided by Sony.
There is a good unlocking-walkthrough at developer.sony.com which I have followed, but not a word about locking the bootloader back.

Now stuck with unlocked bootloader - I can't pay using NFC and some apps do not allow login.

Hi @steev73, I don't recommend unlocking the bootloader as it can cause serious injuries, and some network operators prevent users from unlocking the bootloader. However, you can follow the steps here: https://www.sony.co.uk/electronics/support/mobile-phones-tablets-mobile-phones/xperia-xz2/articles/SX150401 The best option would be to purchase a new device. Stay safe.

No I didn't, but I have moved from Sony to Nothing.
