I’ve found that the ArchWiki is a reliable, maintained reference that usually can be applied to openSUSE with no modification, in the rare instances something specific to Arch is mentioned, is easily addressed.

https://wiki.archlinux.org/index.php/zswap

According to the reference, z3fold should be enabled by default.
