Unfortunately, Alpine Linux kernel configuration disables CONFIG_BLK_SED_OPAL interface required by sed-opal-unlocker: https://git.alpinelinux.org/aports/tree/main/linux-lts/config-lts.x86_64#n852

You can either recompile kernel yourself, or kindly ask Alpine folks to enable it by default.

And btw. if it still does not work after enabling that option, try /dev/nvme0n1 instead of nvme0.
