So. today I mange to patch and flash my X99A 4101 bios. Complete of microcode, MSR 0xE2 register and Native NVRAM whitelist. And again I still rebooting on stage 2. This thing is driving me nuts. I suspect it can be something with my EFI.

Would you mind share your EFI folder?

I attach my bios, EFI, UEFIPatch and the patches.txt that did the work for me
Attached the EFI.zip which I used during Big Sur Installation. I have removed the "Cpuid1Data" under Kernel section and whole entry under SMBIOS section from the "config.plist". So please adjust them to fit your system configuration.

But before moving forward, I would recommend you to verify whether the native NVRAM (patched) on your mobo works as expected.

Good luck.

Hello, can you find a patched x99 deluxe II bios? I generated one myself, but it will restart in the second stage.

Thank you for the link, but I updated the bios file provided, and the same restart occurred in the second stage of the installation.

Seems to be rather old. Late 2019. i think bios 1901 isn‘t latest bios, too.
