The main thing in this json is that only one nsx-t manager (this can be modified to include the other nsx-t managers) will be deploy and no license keys have been added but it is fine to deploy without. This has been tested in my lab with or without VLC. It is for cloud builder input. This is for 4x Nics ESXi hosts and Management / Overlay is on VDS1 and vSAN / vMotion are on VDS2.
