How do I image a LUKS system disk with Clonezilla without including all the empty space?

I have a 1 TB NVMe disk with Ubuntu 22 installed with vanilla options, except I used LVM, and enabled LUKS. I'd like to image the disk for easy restores. Simply backing up the files is not enough for me, because I also want to revert partition/LVM information when restoring. However, I don't want to end up with a 1 TB image file that is 95% empty space. How do I get Clonezilla to do this? I can unlock/mount the encrypted volumes, and image them, but that doesn't maintain the underlying partition structure. If I image the underlying partitions, it images the LUKS partitions like they're just a 900ish GB slab of binary. What's a workaround here?
