Yes, of course. We recommend using a post hole digger because it should be positioned up and down (vertically) and not on its side. Each unit comes with sealant and instructions on burial if you want to do that. The area above where time capsules are placed should be sealed off nicely such as with a plaque installation (see https://www.futurepkg.com/wamu-hollywood-time-capsule) or even with a boulder (see https://www.futurepkg.com/eli-lilly-time-capsule). Never wrap any time capsule in plastic, always use common sense.
