You can. While gpart provides common aliases that make it easier
to work on different schemes without having to know too many
details, you can still use the scheme-specific partition types
if you know them. For example:

        ns1% sudo gpart create -s mbr md0
        md0 created
        ns1% gpart show md0
        =>   1  2047  md0  MBR  (1.0M)
             1  2047       - free -  (1.0M)

New let's create a NetBSD slice:

        ns1% sudo gpart add -t netbsd -s 1023 md0
        gpart: Invalid argument

Uh, ok. No alias know. Raw value it is...

        ns1% sudo gpart add -t \!0xa9 -s 1023 md0
        md0s1 added
        ns1% gpart show md0
        =>   1  2047  md0  MBR  (1.0M)
             1  1023    1  !169  (512K)
          1024  1024       - free -  (512K)

HTH,
