ASUS R4E Cpu clock gen filter does not appear in bios

Good morning. I have a small problem with my bios on a rampage iv extreme bios 4901. When I edit the bios with “AMIBPCP” in the menu there is the option “cpu clock gen filter” while in the bios of the card , this option does not appear. despite several settings, impossible to make this option appear. Attached is the code extracted from the bios with “mmtool”.

Have you tried changing the visibility access from Default to User on the string.

EDIT: Was this the only thing you changed? EXACTLY as you see in the capture screen?
Or the bios has any other mods or changed values?
Did you changed the Default or Fail-Safe to Enable/Disable from AUTO?
How was it flashed?

If no then the mod cant be made with AMIBCP as other modules like AMITSE etc… also needs to be set, in this case use other alternative:
[TOOL] UEFI Editor - BIOS/UEFI Modding / BIOS Modding Guides and Problems - Win-Raid Forum (level1techs.com)
[GUIDE] Usage of AMI’s AptioV UEFI Editor + FPT Flash Method - BIOS/UEFI Modding / BIOS Modding Guides and Problems - Win-Raid Forum (level1techs.com)

when I modify access to visibility as you recommend, the pc no longer wants to start, it starts for 2 seconds and goes out in a loop.

hello yes i modified it with amibcp v4.53 in the tab “Access/use”.
I flashed the bios with " USB BIOS FLASHBACK" as per usual. it’s a bios with some changes like:

NVME support, Biffurcation, pci subsystem seting, microcode, resize bar.

in the tutorial, you have to use “IFR EXTRACTOR RS” but it doesn’t work.
