It is possible to bury kitchen scraps in your garden, but it is not the most effective way to compost them. If you bury kitchen scraps in your garden, they will decompose more slowly than if you compost them in a bin. Additionally, they may attract animals that will dig them up. So, be sure to bury them deep enough that animals can't reach them, and be sure to bury them in an area that won't be bothered by the smell.
