Tested with Big Sur but probably will work with Catalina as well.
I am not a specialist and I spend a lot of time to make my system work.
In my opinion, I assume that it is a very common low budget hardware combination.
So, I am placing here my files to save you some time.
You have to import your custom System Serial, UUID, and MLB numbers.
Working everything except sleep/wake (you have to unplug and plug the display cable).
Easy fix = Disable your display turn off in power settings.
Of course, if anyone find an 100% solution, I will be gratefully to hear about it.
There are two versions:
Final = For exactly same system with theme, modded USB3 and LAN kexts
(The OpenShell and Clear NVRAM tools are hidden under spacebar)
Debug = For experiments on similar systems with detailed debug info and original kexts
(You will probably need to generate your own ACPI SSDTs)

=============== EXTRA DETAILS ===============
- Due to security reasons Apple does not allow non certificated extensions to get installed. So, I have put NVRAM/Add/7C436110-AB2A-4BBB-A880-FE41995C9F82/csr-active-config = 03000000. You can change it to 00000000 if you facing updating problems.
- If you experience boot loop after partition scheme modification consider of changing the SecureBoot flags (not tested).
=============== HELP ME AND OTHERS ===============
If you have any success to other systems with those EFI folders please mention it on Issues section among with the tweaks you have made.
Thank you.
