Help needed to remove intel microcode from LENOVO AMI Aptio V ROM to get oerformance back for dual Xeon's

Hi,

I have a Lenovo P900 Workstation with dual e5-2698v3 and I would like to have the two intel microcode sections removed so that the original errata from Intel that allows to Turbo all cores to MAX is permitted.

I’ve followed countless guides and the problem arise when I try for flash the modded BIOS Code 18 Security Flash fail Error 24…

Can anyone help? It’s a C612 chipset
