Even if this did happen, there's a trivial workaround available: Just go into your BIOS and switch 'Secure Boot' off.
Secure Boot is a fine thing if you're a huge corporation and want to harden laptops against untrustworthy employees, or you've got such a huge fleet of servers they go missing despite your physical security controls, or you're making a TiVo style product you want to harden against the device owners. But when the user is the device owner? Doesn't do much.
