pkgsrc, 'the portable package manager', support Apple Silicon:

http://pkgsrc.org/

No binary packages yet, but using it from source is pretty much a matter of downloading and extracting the 'current bz2', then:

    cd pkgrsc/bootstrap
    ./bootstrap --prefix=/opt/pkg

The default prefix is /usr/pkg, but that's protected by macOS' SPI. You might want to add /opt/pkg/bin and sbin to your $PATH. Then to install a package:

    cd pkgsrc/sysutils/nnn
    bmake install clean
