Enable secure boot on ESXi server after install

[baber]

I have installed esxi 7.0 U2 and my server is DL580 G10. My server support secure boot but it is disable .

 What will happen if I enable it in my Bios now ? Will not happen any problem for my esxi ?

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.
