Any updates on this? So what is the chipset driver I should run and is there any performance hits? 

First, have Windows install chipset drivers (that is done through Windows Update, under Optional Updates), don't use EVGA's.
 
Next, after that you will most likely find Device Manager complains driver is missing for four "Other Devices - Performance Counters". These devices are "Intel(R) Xeon(R) processor P family/Core i7 DDRIO Registers - 2088" and drivers for them used to be included with Intel’s chipset drivers (latest release I could find them in was EVGA's 04/17/2020 V 10.1.8.6 release of X299 chipset drivers) but they are not part of Microsoft’s distribution of chipset drivers through Win10 Optional Updates process.
 
So correct way to address this is to:
 
1. After you have applied Microsoft’s latest distribution of chipset drivers through Win10 Optional Updates process extract ZIP with EVGA's 04/17/2020 release (V 10.1.8.6) of X299 chipset drivers into temporary folder (you don’t need everything, you need just files that are in \DriverFiles\production\Windows10-x64 subfolder).
 
2. In Device Manager right click on first "Other Devices - Performance Counters" device missing the driver, click on ‘Update Driver’, when asked how do you want to search for drivers click on ‘Browse my computer for drivers’, click on ‘Browse…’ and navigate to and select temporary folder containing files you’ve extracted from \DriverFiles\production\Windows10-x64 in previous step.
 
3. After first one is done update driver on remaining three (this time you can tell Windows to "Search automatically for drivers" because after first one is done Windows will have copy of it in repository).
 
4. Delete temporary folder created in first step.
 
Note:
 
Missing drivers seem to be distributed through Skylake-ESystem.inf and related skylake-e.cat files. Look at Skylake-ESystem.inf shows comment “Assigns the null driver to devices for yellow-bang removal and  brands Intel(R) devices“. Search for DEV_2088 device shows description Needs_NO_DRV.
 
In other words everything indicates devices in question don’t need a driver and that EVGA installs null driver for them in order to avoid user confusing warning marks by Device Manager. In turn that means Intel/Microsoft not having them doesn’t result in actual functional/performance issue/difference but “just” aesthetic one.
