Hey, do you have any guide on how you managed to do it?
I have the same board and I would like to do it!
@neyox24992 - No, sorry, there is no guide for this, it’s kind of involved due to the NVRAM edits required, that needs it’s own guide first which I’ve not had time to do yet.
I replied on your thread
@Lost_N_BIOS May I please get a new link for the f11e bios for the Aorus master you modded in post #30, tinyupload is no longer working.
@Teeeee - Thanks for report, yes, Tinyupload has been down for a week+, hopefully they come back soon 
New mirror added at #30
Is there a version of the latest Auorus Master BIOS (F11l) anywhere with just HPET hard disabled?

@ZAU - Z390-Aorus-Master_F11L HPET Hard Disabled - http://s000.tinyupload.com/index.php?fil…721462700058333
Flash via Qflash, clear CMOS once done, then enter BIOS and load optimized defaults, save and reboot back to BIOS to make rest of your changes (Don’t used previously saved profiles, it may contain HPET enabled, I am not sure)
Thanks I appreciate the time. I have flashed it, cleared cmos etc however HPET is still showing in device manager. Is this normal?
@ZAU - You’re welcome! Yes, this is normal, due to how Win10 uses this timer now vs previous windows -
See my testing done at link below, in case you already messed with BCDEdit, because my testing shows that with HPET disabled in BIOS any change you made with BCDEdit in regards to this should be put back to the default, if you never changed anything with BCDEdit then you are good to go 
See below “Change Log” area for HPET test info and image - [OFFER] Gigabyte Z390 M Gaming UPD + Completely Revised Blue Theme

Hi, I would like to download this but when I click the link it doesn’t show anything. I really want to disable HPET in my bios. Can you help me pls?
HI! I’m downloading it right now and will test it right away. Hpet is already disabled in bios right? No need to do extra things?
Here is descriptions :
1. RST UPD (BOTH = EFI/SATADriver + oRom) 17.7.0.4404 >> UPD To >> 17.8.0.4507
2. HPET Hard disabled >> You should still >> BCDEdit.exe /set useplatformclock no
3. RGB Fusion unsuppressed (access via "Bug #2 only)
4. Qflash Unlock (In BIOS F11e >> This = BIOS as a whole, hex edit @ 0xFD31C7, change 01 to 00)
