Questions about Anti roleback

Hi there
I've read I couple of thread regarding the ARB(Anti roleback) from Xiaomi on our devices (MI8, Dipper)
and I have some questions:
Now I am wondering how and when this will be triggered?
What can/could/can't I do source it's triggered?
Can I flash an Android 9 ROM and revert back to an Android 8.1 ROM?
If the ARB only relevant for Stock MIUI ROMS or also for Custom ROMS?
(More personal)
I am currently using Xiaomi.eu rom 8.8.30 MIUI 10 (Based on android 8.1),
I would like to flash the Andoid 9 variant, but I am scared of bugs and I want to know if I can revert once I flashed Android 9 or not?

Help me with antirollback issue with CC9 (pyxis)

My CC9 is currently on Stock MIUI 12.0.2.0 stable (QFCCNXM)
Android version: 10
I checked ARB via fastboot commant and got "anti:1"
My question is .... "is there any way to flash Android 10 based EU custom rom running MIUI 11.0.3.0 ?"
That means I want to downgrade from stock miui 12 (Android 10) to custom miui 11 (based on Android 10) or custom miui 11 (based on Android 9)
via TWRP.
Is this will cause hard brick?
Please, someone clear this confusion...

Thanks for the response. I know how ARB works in switching official miui.
We can check the antiroll back index from fastboot rom image (from bat file) but since I want to move from an official miui12 to a custom xiaomi.eu miui11 so how can I check that xiaomi.eu rom's ARB index? because custom roms are recovery rom to to be flashed from within twrp. Is there a way to check ARB index of an recovery rom?
This is where I got confused that switching from official miui to a custom miui will still get affected by ARB or not...

Yes , there is hope. But we need a custom recovery first , TWRP or AOSP recovery it doesn't matter

seems that twrp is out, now waiting for some developer to make a custom rom, and hoping that battery life can get better than stock rom.

Even so, this twrp that just released is based on A10, so u can only flash magisk but cant flash any A11 roms as of yet

What do you mean it can only install Android 11 ROMs? People are using the Mi 11 TWRP to install xiaomi.eu MIUI 12 which is based on Android 11:

Hello!! , so as you have all seen, Android 13 GSIs are available, but here is the thing, i never installed a gsi on my phone (redmi 9A) the only time i installed a custom rom was Arcana OS (A12)
My question is: how can i flash a gsi img of A13 into my phone ?

Question Android 13 GSI

Hello,
I could see that GSI for Andoird 13 is available, can we install it? or there will be some problem due to stock ROM having vbmeta for Android 12 only?
