Yes, i also doesn't remember where it can be read. Only in g_part_mbr.c :)
Try this:
# gpart set -a active -i 1 ada2
This will set active first partition on ada2:
# gpart show ada2
=>        63  1250263665  ada2  MBR  (596G)
          63    40965687     1  !7  [active]  (20G)
    40965750  1209292875     2  !7  (577G)
