Yes. FreeBSD supports nosuid mounts. With ZFS, it's even an
inheritable property on the dataset. In either case, just running
`mount` and looking for the mount-point where the binary lives should
reveal it.

Eg:

  # mount | grep music
  cast/media/music on /mnt/cast/media/music (zfs, local, noatime, noexec, nosuid, nfsv4acls)
  # zfs get setuid cast/media/music
  NAME              PROPERTY  VALUE   SOURCE
  cast/media/music  setuid    off     inherited from cast/media


Hope this helps with debugging,
