Hi,
I think you are asking:
"If I use an iSCSI storage for a proxmox backup over the internet, will it be encrypted?"

Perhaps a better way would be to backup to a local storage and then use an encrypted file transfer to your offsite backup? ftp is not an encrypted protocol but you could use sftp, ftps, scp, rsync, etc.

I hope that I have answered your question.
