As i was installing\upgrading my lab environment to ESXi 7.0 i received an error that the CPU was unsupported. As per the release notes vSphere 7.0 release notes my CPU is no longer on the compatibility list.
Since this is a lab environment i wanted to continue using my current hardware. It goes without saying that this method should not be used in a production environment.
To allow the legacy CPU all i had to do is boot up from the ISO, on the boot Menu i pressed TAB or Shift + O and added allowLegacyCPU=True option as seen in the screenshot below
