unlock bootloader ; see https://www.hovatek.com/forum/thread-29918.html
download global fastboot rom @ https://c.mi.com/oc/miuidownload/detail?guide=2
flash global rom using miflash ; see https://www.hovatek.com/forum/thread-27300.html

when flashing do NOT select "clean all and lock" as it will relock your bootloader and if anything goes wrong you will no longer will able to flash using fastboot (you'll either need service center or an authorized account to flash)

XR7a runs on qualcomm chipset, any qualcomm backup method (you can use the search bar at the top of the top) will work only if you have the right firehose programmer file for your device and can boot into edl mode. Firehose file for this model is not readily available so backup will not be possible but on the bright side, xiaomi releases their firmware so you can easily search for your current firmware build and download it's fastboot rom which you can flash if the device bricks. So long as you don't lock bootloader while flashing the global rom (the reason i mentioned not to use clean all and lock)
