With the upcoming release of vSphere 7.0 Update 1 and specifically ESXi 7.0 Update 1, support for the onboard NIC of the Intel NUC 10 (Frost Canyon) is now included and the community ne1000 VIB driver is no longer needed. If you had previously installed the community driver, you can uninstall the VIB after successfully upgrading to ESXi 7.0 Update 1.

For Intel NUC 10 (Frost Canyon) owners who have installed ESXi may have noticed that even after disabling Intel's Trusted Platform Module (TPM), the following warning message "TPM 2.0 device detected but a connection cannot be established." is still being displayed in the vSphere UI as shown in the screenshot below.
Thanks to Reddit member mscaff and casperette who recently discovered and confirmed that the latest BIOS (FN0044) resolves an issue where disabling TPM in the BIOS was not actually working which would explain the behavior observed above. The really interesting thing is that I had initially ran into this problem several months back and after speaking with some internal VMware folks, I was able to get rid of this message without this update. This involved installing Windows 10 and clear the TPM keys which may have still been cache but since then, it has not been reproducible by other folks. In any case, it is always recommended to check and update to latest BIOS to ensure you have all the latest bug fixes.
Lastly, Intel states support for TPM 2.0 for these NUCs, so why is ESXi complaining? Well, it has to do with the interface type and not with SHA1 vs SHA256 which are both supported on the NUC 10. The NUC only supports CRB but proper compliant TPM 2.0 chip must support FIFO which is not configurable the last time I had checked. For more detail requirements and configuration of TPM 2.0 on ESXi, please refer to this blog post.
As many of you know, the onboard Intel NIC (8086:0d4f) found in the 10th generation of the Intel NUC (Frost Canyon) is not automatically recognized by ESXi and requires an updated ne1000 VIB which was released earlier this year. An unfortunate side affect after patching or upgrading an ESXi host which contains this modified ne1000 VIB is that it will be replaced by a newer version of the VIB and causes the NIC to no longer be recognized again.
A quick workaround is to simply re-install the modified ne1000 VIB and network connectivity will be restored which is less than ideal. A new vSphere Image Profile can also be created that contains both the patch/upgrade you intend to apply along with the modified ne1000 VIB, ensuring that you remove the newer version which may not be ideal as well. In speaking with Songtao, a VMware Engineer who I worked with on the USB Network Native Driver for ESXi, about this issue and he came up with a very simple solution. Lets choose a different name for the VIB module which removes all the complexity mentioned above. This solution would allow for both drivers to coexists and more importantly, it is persistent across patching and upgrades of ESXi.
