Well, you can't encypt your root partition while you're booted into it so you'll need to use a live environment but it should be possible to enable full system encryption
You'd likely end up using cryptsetup-reencrypt to convert your partition over to using LUKS
sudo cryptsetup-reencrypt --encrypt --type luks2 /dev/sdX
you'd then want to decrypt and mount it before trying to chroot into your system
sudo cryptsetup open /dev/sdX root_encrypted
sudo mount /dev/mapper/root_encrypted /mnt
with that done you can add the encrypted partitions UUID to /etc/crypttab
you'd probably then need to rebuild initramfs via dracut and maybe also update grub.cfg to ask for a password - not sure if it does so automatically or not
i'd recommend double checking that but hopefully that provides some guidance in what you're looking to do
