If the Secure Boot certificate is not updated on a small set of machines before the deadline and the certificate expires, what would be the recommended next steps to remediate those devices?

Hi VaishnavK1993.

the devices will continue to boot and operate normally. The steps to get them remediated are the same steps as before the certificates expire.

Test devices and apply across the devices. Update firmware where necessary.

There are a lot of good resources at this link below and these resources are being updated regularly.
