I'm making an Eevolution team, and I'm aware that Hidden Power can be a ground move, but is there any other move?
Only four unfortunately.

It can learn dig, mud slap, and sand attack, all of which are basically useless. So if you really want a ground type attack, go with hidden power. Source: http://www.smogon.com/bw/pokemon/glaceon/moves
Dig Sand attack Mud slap(only with gen4 move tutor)
Yes, it can.
