I apologize I’m not looking at the gui at this second but I don’t believe they exist. Firstly, Luks 2 has some support in grub now, so should be accessible for
/boot. Secondly I’d like to see these options
it might be a good idea to detect an SSD (probably the most common now) and auto add the last 2. Since discards can affect security an advanced checkbox with a warning in red would be a good idea.
