Yes, using any number of tools, including LUKS.
Is it possible to encrypt your root partition at any time? Not while the
system is running, as far as I know. If it is, its not an easy procedure. Its
best to encrypt your root partition at install time (which the Debian
installer will allow you to perform).
Is it possible to encrypt your /home partition at any time? Yes, but its not a
straight forward process. It can definitely be done while the system is
running, but its not recommended.
If you feel adventurous, check , the tool "luksipc" is in Debian
Buster/Sid. It goes without saying that a couple of recent backups are a
must before trying this. It doesn't work from the running system though,
and you need to read the "disclaimer" part first (specially the part
about disk with read errors) .
LUKS has come a long way, it is now possible to move (even to the
previously dreaded "left" of the disk) and resize a container with
G.U.I. tools like "gparted" or KDE "partitionmanager". Not yet from a
running system but it is getting much easier. "luksipc" worked well for
me but only on test systems with little data and simple setups, so I
can't vouch for it besides the sandbox use-case.
