    I think that you need to new installation after enabling Secure Boot.

    I did it on my lab and nothing happen but the number of VMS on that host in my lab was a few and in Production Env there are a lot of VMs on my host . So I want make sure to do it before any change.

    I changed it in my production env and no need to reinstall ESXi .

    Secure boot can always enabled after installation of ESXi and adding "needed" 3rd Party VIBs because there is a test function available to identify vibs without a valid signature/certificate.

    /usr/lib/vmware/secureboot/bin/secureBoot.py -c

    If you pass that step you can easily enable secure boot within the Server BIOS/Setup during a reboot.
