Most of the "Secure Boot" hardware I've gotten my hands on have been early generations, up to some produced in 2015. I've had to change the mode to "deployment" on some HP ProDesk systems in order to get it to install Fedora, for example. I can't speak for the most recent generations, but I remain skeptical due to the "lockdown" functionality breaking everything. Other times you'd need to do so are when you'd like hibernation support, any out of tree modules such as ZFS, kexec, hot patching.. -- John M.
