How to relock bootloader on Poco X4 Pro 5G (veux)

[txt_hnc]

Hi everyone,

I have a Poco X4 Pro 5G (veux) with an unlocked bootloader. Currently, my device is running crDroid 10.9.
I'm unable to use my banking app, which I suspect is due to the unlocked bootloader. Therefore, I'd like to relock the bootloader.
Could someone please provide instructions or guide me on how to relock the bootloader on this device?

I am using a MacOS Apple Silicon computer. Is it possible to perform the relock process using my Mac? Any specific tools or steps I should be aware of for MacOS?

Thanks in advance for your help!

If you want to lock the bootloader you need to install a factory/official ROM.
I can provide you with a guide but it is for windows, https://xiaomi.eu/community/threads/how-to-install-stock-rom.74017/post-734380
