Here is how I was able to install ESXi 8 onto my Intel NUC 12 Wall Street Canyon
Press Power Button
Press F2 to get into the BIOS
Navigate to the Power, Performance and Cooling tab
Select External Ambient Temperature
Set to User Defined
Mouse over to Performance and click on it
Set the number of E-Cores to 0

Now you can reboot and install ESXi
