Currently running the latest 1903 BIOS and after spending way too long looking for what I now know is a hidden HPET setting I thought you guys might be able to help!
I found one other request back in 2020 but the file is no longer available to download.
If anyone can help that would be awesome! 
I know someone must be up to the task! I can offer a pre-emptive THANK YOU to anyone who is willing to help out!
This model has no USB BFB function so it has increased risks after a failed mod/flash, u need to unlock bios regions, dump with Intel FPT tool, edit the dump with AMIBCP/IFRextract Hex edit and flash it again with FPT.
Try some guidance on other similar requests on the forum.
Thanks for the heads up, appreciate it!
