Downgrade to official global rom

[Cloud_Rainy]

Hello, I currently have the xiaomi.eu beta rom on my poco f2 pro.
I need to reset it to the factory state, by that I mean, install the official global rom, close the bootloader as well as remove the custom recovery and any traces of the rom.

Informed, but I would like to be sure of the procedure, so as not to brick my device (close the bootloader with a custom rom) ..

If you could help me, I would be happy to!
