Did 20.04 drop full disk encryption?

A low tech user here. I did not see the check box about full disk encryption when I installed 20.04, so it looks like it is no longer available. I reloaded 19.10 for now. Can I keep full disk encryption if I update from 19.10 to 20.04?

So far I have not had success getting my computer to upgrade using the alt+f2 commands in the release notes. But if I can't keep the encryption, there is no point pursuing the update. I will just start over with a fresh install since my settings are already gone.
