I remember reading a post on mastodon where it was explained that no mother board validates the secure boot keys expiration dates otherwise it wouldn’t boot the first time the BIOS battery gets empty and the internal clock gets reset.
The post was written well and was citing some sources. But I didn’t try to verify these assertions.
even if it did, its not like any existing motherboard requires internet to boot, you can just change the MB clock to be prior to the expiration and theoretically it should boot regardless of restrictions.
