Maybe or maybe not, usually the MW FW is not touched by bios region update, unless the Dell update payload requires to update to a new ME FW image version.
Assuming the changes were only made with FITC in ME FW region.

Dell ‘bios’ updates often contain ME updates. Since an ME update will update the code partitions of the ME but not the data partitions the settings will be kept.
(Exception would be if the vendor decides to replace a complete ME region, quite seldom for bussiness machines)

Thank you for this summary.
Encouraged by your efforts I bought a CH341 programmer & clip and got to work, and now I have Optiplex 7010 Micro with enabled AMT.
I had problems with writing to the chip (it wouldn’t pass verification) and I almost gave up blaming it on a bad CH341 (tried a different computer, usb port, one clip and IC clips). In search of new hardware programmer I found this page about CH347.
And finally Shichang Zhuos open source programmer from that page did the trick (it also works with CH341). I had an impression that it was slower than other programmers, so I guess that it maybe worked on lower speed and that is why it hadn’t failed.
Thank you for this guide. I went through this for a Dell OptiPlex Micro 7010 (13th Gen).
Got it with a “3, Disabled” sticker and no Intel AMT.
The chips on mine are both Winbond and placed slightly differently.
I managed to dump the Winbond 25Q128JVSN with asprogrammer to obtain the current Intel ME firmware.
Besides your above procedure, the Intel ME for the bios version on mine (v1.30) was 16.1.38.2676.
I used the firmware file from https://fwupd.org/ to extract an unconfigured matching Intel ME: LVFS: OptiPlex Tower 7010, OptiPlex Micro 7010, OptiPlex SFF 7010
As a new user, unable to upload attachments, but I can provide “CSE ME 16.1.38.2676 Prod CorpH Unkn ADPRPP.bin”, if anyone needs it.
It can be extracted with Dell-PFS-BIOS-Assembler.
Note that UEFITool gave errors on my combined BIOS, but MFIT was able to Decompose, modify and construct a new BIOS just fine.
Happy to report success after rewriting the Winbond chip! Intel AMT is now enabled and working as intended.
Hello! I just bought Dell 7020 Micro with i5-14500T. It has 3-Disabled sticker on it, like described above. Is there a possibility that instruction will work for my model? What should I check?
@snake007uk and @lfb6 Thank you very much! You are the Best!
Followed your instructions and I have successfully enabled AMT with KVM on my Dell OptiPlex 7020 Micro. Just for note - it was a model with i5-14500T, factory Bios 1.10, ME CorpH firmware v16.1.32.2418.
PS: Just wanted to add that I successfully updated BIOS to 1.22.1 with ME 16.1.38.2676 and AMT configuration is still available.
