Sounds like not postmarketOS specific packages, but rather ones that would go into Alpine. You could make a packaging request here, and maybe someone wants to package it and maintain it for you if you are lucky: https://gitlab.alpinelinux.org/alpine/aports/-/issues/
Or you could try to build it yourself (and if you are willing to maintain it, then get that package into Alpine). Building Alpine packages is relatively easy: https://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package
