How to create a custom ESXi 6.5 ISO with VMware Image Builder GUI – ESX Virtualization

So in my lab, I was able to add custom drivers and remove drivers from the original VMware ESXi 6.5 ISO. The resulted image was then exported as ISO or it can be used for AutoDeploy scenarios. You might also need to create a custom ESXi 6.5 ISO when you need to integrate other than the stocked VMware drivers, say you have a NIC card which has it’s own drivers.
