Antiroll back number flashing

[Thomas_xxxxx]

Hi, can I flash MIUI ROM which has this in flash_all.bat:
if [%CURRENT_ANTI_VER%] EQU [] set CURRENT_ANTI_VER=0

when my current ROM after running "fastboot getvar anti" returns 1?

Will XiaomiFlash prevent me from bricking when trying to flash something with lower antiroll back number?
I have Redmi Note 8 Pro
