At the moment, my LXC container is running Debian 10 on ext4 file system. The Container is stored on the same disk where is running Proxmox (/var/lib/vz/), and this latter is using ext4 as well. If I convert my LXC ext4 file system to ZFS then will I able to take Snapshot? How can I convert it?

You need to convert the host storage to ZFS. You can do this by reinstalling. Backup all your VMs/CTs to an external storage, reinstall PVE with ZFS and restore all you VMs/CTs

ZFS heavily trades IO performance for caching / RAM consumption. So if you have enough RAM, your IO will be even faster than before. If you don't have enough RAM, the IO will be slow and RAM occupied.
