there are different Motorola One's, and not just on region specific, but features, broadband and carriers (One, Fusion, Fusion+, Power, Vision, Action, Hyper, Zoom (Pro), 5G, 5G+)... you need to be more specific, and if you cannot find it on XDA forum, you will probably have a hard time to lay hands on it...

I have the same board (Atermiter X99H-D4, Intel B85 (Lynx Point)) but is V1.3, that refer to the System Board "Revision" version, not the BIOS ver. (BIOS Version/Date: American Megatrends Inc. 5.11, Tue, 8/10/2021; SMBIOS: Version 3.0). when I got mine, I did a search for the same thing, the latest BIOS, it happen that there is none, what I found were "modded" BIOS, meaning, with the CPU "Unlock" enabled, tweaked mV, etc) but still no luck for a "sleep" fix, can only do hibernation. I did NOT flash the Motherboard with others people settings, because there are some values that are for specific CPU's models that can do heavy damage to others, instead, so, what I did, was to do the unlock manually, by myself, with a X99 BIOS editor with specifics for the E5-2660V3. Look for "X99 Turbo Boost Unlock - Once and Forever" it will list a link that will take you to a guide with a "How to" ...

I have the exact same Atermiter mainboard, with "X99H V1.31" printed, your BIOS file have the CPU "unlock" enabled?, does it work for E5-2660V3?
