As many of us early adopters have been moved to legacy status I am making this pretty simple guide. None of the ME firmware available in the BIOS files posted here are vulnerability free. For those of us deprecated years ago, the list is LONG. There are tons of vulnerabilities. If your ME Firmware is not up to date, here is a list of such vulnerabilities. Check the publish date of the latest ME updating BIOS for your card and that's a good estimate of how many are left unpatched.

Someone had a corporate board and failed flashing.https://rog-forum.asus.com/t5/hardware-build-advice/index-all-my-firmware-drivers-software-threads/m-p/827232 Find the download you need (comes with the official Intel ME FW and patcher). Right click start, click device manager, and make sure under system settings you have your current or newer Intel Management Interface installed. If not, check if Windows will install/update it for you or go grab it from EVGA downloads.
I had no issue, but consider being sure your vital data is secured if you use virtual TPM, such as a system image or duplicate files on another drive. I run BitLocker on my OS drive with the ME's virtual TPM and had 0 issues booting after patching, but I have dual bios and my recovery key on hand, and learned the FW patch enters an area of BIOS reserved for it so didn't have 2nd thoughts about going ahead and backed up nothing. Up to your discretion. Extract the files and run install.bat as admin. Do not lose power or shut down! After a moment, boom, holes filled. Reboot.
For me on Z170 Classified K, the number of holes was 9. BIOS 2.06 from Jun 2019, but ME FW of April 2019 as verified by AMIBCP. BIOS intact, now with ME FW 11.8.93.4323 and no known holes more. Finally, enjoy your sense of security!
