    Lock it the same way you unlocked it. Simple.
    There are guides in xda.

    use msm ,if you try to forcefully lock the bootloader you might hard brick your device

    Google it man
    msm for "your device"
    see some instructions
    it's pretty easy

    Please don't relock bootloader, it may cause hard brick in this lockdown period... btw i can help you in using banking apps with magisk installed at the same time...

    Most banking apps detect unlocked bootloader now. Magisk is useless in those cases.

    You are right, but in India, BOI, SBI, HDFC etc banking apps are working fine. I'm using it in my rooted Redmi k20 pro by changing the package name of magisk and saftynet check passed...

    Oh! I thing you should wait for more development. I would like to say relock bootloader only if your device is in warranty period so that if something goes wrong, you can get motherboard fixed by service center.

    I did this already on my OnePlus 6. I tested the Developer Preview and some Custom Roms so I needed the unlocked bootloader.

    I first reinstalled OxygenOS. You should do it on both Slot (A/B). Maybe this is not needed.
    When the original firmware (OOS or H2OS) is reinstalled, boot the phone to fastboot and type:
    fastboot oem lock

    Have to reset your phone and your bootloader is locked again.
    Google Pay, Netflix HD playback and everything else is working.

    You should not lock the bootloader when your phone is rooted or you have a custom rom installed.
