Intel XTU and ThrottleStop no longer working to undervolt Xeon E-2186m after firmware update

HP Recommended
ZBook 17 G5
Microsoft Windows 10 (64-bit)

I was using ThrottleStop to undervolt the Xeon E-2186m on the ZBook 17 G5 to reduce temps, and everything was golden until applying the latest firmware. MB BIOS Q70 Ver. 01.09.01 and CPU microcode Revision BA are installed.

If anyone with an HP Probook, EliteBook, or, especially a ZBook that has the latest firmware could please check if you are able to still undervolt with TS or XTU, I would be interested to see if it's just my system.
