It's not possible to downgrade from 18.04.6 to 18.04.4. It would break too many packages. Instead of downgrading from 18.04.6 to 18.04.4 it's possible to download Ubuntu 18.04.4 and replace 18.04.6 with 18.04.4 by selecting the Erase Ubuntu 18.04 and install Ubuntu 18.04 option in the Installation type screen of the Ubuntu installer.

Unfortunately this will will completely erase your current Ubuntu installation with all programs and settings. If you are willing to take this drastic step please backup your stored personal files first. Don't select the Download updates while installing option in the Ubuntu installer, otherwise it will undo all your work by updating Ubuntu 18.04 while installing it.
