Z490 VISION G (rev. 1.x) support
Latest bios version is F20d (2021/03/12)
Update your bios if you have not already
Your device is still supported and will likely receive further updates.therefore it would be best to disable Hpet in OS level

Thanks for the quick reply, does 20d now have a disable option, I remember it used to be on the an older rev. maybe 6.

well I just upgraded done see a HPET option in the BIOS, so, back to the original ask for a HPET edit. , not sure if just a windows disable is enough.

Not everyone is noticing improvements after disabling HPET in both the BIOS / UEFI and the Windows operating system.
But for some disabling it in OS is the end of it
And some notice improvements and micro-stutters go away after disabling it on their OS regardless the bios setting
