Need help on downgrading

Hi xda members. I recently bought Mediapad M3 device BTV-DL09C209B312. ((I wanted to unlock my bootloader on ministryofsolution website for $4. the problem is, it can only be unlocked if the device were on july 2018 security patch or below. My current security patch is on november. My question is, is there any reliable tutorial to downgrade this device and unlocked it? I am afraid of bricking the device and i am not really familiar with huawei)) Please tell me step by step and what to do and what not before/after unlocking the device. Such as, do we need to save efs backup, imei, keys, oem info, any other important partition or something like that as long as it is important for huawei user. Thank you. I really need someone to guide me. Your help is really appreciated.
Edit: Skip the part for downgrading with bracket(()). Actually the unlock is supported and i misread the part where "EMUI 8 with july 2018 security patch above are not supported"

[Nokia 6 TA-1021, Android 9] Is this phone rootable?

Hi. I wanted to get root in my ohone, but any tutorial I followed is useful. I can't use SuperSu and TWRP methods because I can't unlock the bootloader and the app Nokia gives in the official page for unlocking is completely useless. Better not even talking about the one click root apps because I am not even going to pretend they exist.
So I don't know what to do. Some people says this model is completely impossible to root, while others recommend I use Magisk (I don't know how) or specific commands in the Minimal ADB blackboard, do I don't know what I should really do.
So if there exist a way I can root this model of phone which again is Nokia 6 TA-1021 with Android 9, I would like to know the options and how to execute them. Thanks!!

Since pie update, twrp is not booting in some devices of nokia 6 (TA-1021)
and if u want to root your phone
It's must to unlock your device bootloader first .
After that you can flash twrp and magisk ..
But keep in mind ..
Magisk 17.1 is working on Android pie or else canary build( i haven't tested it yet)
And if you want to unlock bootloader of your phone then u have to buy unlock key .
Or else you can try the procedure as mentioned before by @Calyxhikari.
Follow that procedures carefully.. hope it will work for u

Thanks for the reply.
Yes I concluded the issue is being unabled to unlock the bootloader but I am a bit lost.
How to do it? And also, you menctioned I have to buy a key... There is absolutely no other way of doing it? Am I forced to spend more money or there exist a free way?
I never had to unlock it before and I don't know the process.

It's not expensive , you can buy it from techmesto.com
Or contact to calyxhikari i bought it in just 250rs (INR) And believe that was very simple process to unlock bootloader some commands are necessary to unlock it and that's the only way to unlock it . Once you buy it, then you can lock and unlock it anytime .

Does Calyx Hikari know the keys or what he does in the process?
Also, he also sells the key or he just can help?

To get the bootloader unlock code you have to downgrade to Nougat (via HiSuite) then you can buy the code. (for 4euros).
Bootloader unlock code for RNE is available with this paid service - hcu-client.com or dc-unlocker.com

The unlocked bootloader warning is Android functioning as intended. See Android Boot Flow.
Removing it involves modifying the bootloader, which can brick your device.

There's a whole thread for it here that quite frankly sounds very complicated and not worth the hassle. As @V0latyle said - if you mess up you could brick your device.

thanks guys for the answers
