If you have an error and cannot change the MAC address of your ESXI VM like this one:

Impermissible static ethernet address XX:XX:XX:XX:XX

You can edit your vm, go to advanced options and ADD A KEY

ethernet0.checkMACAddress = "false"

It would look something like this:

Then you can add your MAC and boot the VM like normal.
