Z390 Asus Maximus XI Extreme weird issue

[derril]

Hello guys, first of all i am not sure if my post is in the correct category. I'm going to try to keep this short but it will still be a pretty big read so here it goes: I have bought this motherboard about 5-6 years ago from an online store in Portugal even though i live in Spain, there was no stock anywhere even amazon failed. Ever since i built this PC i always had stuttering issues in online games, i blamed it on the internet, the gpu, the ram, electricity, pretty much everything you can think of. A few months ago i decided i had enough and started tinkering again with the OS and i eventually found out that my PC is falsely half enrolled into something called Azure/MDM/Intune/Autopilot. It does this everytime i connect to the internet. I tried a lot of things, the last 4-5 months i probably had more than 80 formats. I modified isos with NTLite i used autounattended.xlms etc i even tried to firewall block pretty much all Microsoft IPs which works partially untill it doesn't.
So the thing is that i cannot get rid of this issue, i've been trying MS support, Asus etc you name it every day they just send me between them and honestly i am tired of it. It seems that what i really need is a good method to change HWID so that Windows says it is not activated. I did try lately to change .rom with HxD and the afuwin-3.05.04 which it worked half way at least for a few boots. Problem i had is that somehow my Intel Ethernet adapter stopped working which isn't really an issue for me as this Motherboard has 2 BIOS chips and even if i brick one i still have the other.
I bought an original Windows key in hope that it will overwrite the one stored on MS servers but that doesn't work either whatever i do this Windows Enterprise key overwrites everything and executes some custom .ppkg files (i did try to change default app for ppkg files to notepad).
Is there anything i can do to fix this please i am soooooo tired of this issue all i want is to unlink my PC from the Enterprise key forever, i do not have any game bans that would be the least of my issue.
I am not a professional but i do understand a bunch of stuff and i am also very fammiliar with terminals so there is no problem. Also is there any way i could get to downgrade Intel MEI or overwrite it? My goal is to completely reset the mobo as it was when i got it, RAM training and everything from scratch.
I also attach a few screenshots so you can see what i'm talking about so even though i am using Pro the registry has Enterprise entries. Yes i already tried (me and a bunch of ms help agents) to change them and custom install again it always shows up as Enterprise as soon as i connect to the internet and Event Viewer spits out UserDeviceRegistration each boot. It's much more to say but these are a few good examples. Also the last MS agent told me that this happens because i have an Enterprise code embedded in my mobo (OEM) but i am sure i don't because when i open RW Everything and try to look for the ACPI > MSDM i cannot find it...

If you need me to upload anything please let me know, also if you want me to pay i have no problem with it.
