DeepIn 20.2.2 has been released and now supports Secure Boot.
My DeepIn 20.2.2 Written Installation Guide has been updated to configure the Dell UEFI BIOS to configure Secure Boot however I have not updated the tutorial video as changes otherwise are minor with respect to DeepIn 20.2.1 and this Linux distro still lacks support for a 2 in 1 touchscreen device such as auto-rotation and a touchscreen keyboard.
