Dear,

D.el.ed is diploma in elementary education. D.el.ed will basically train you to teach well to your students. If you want to pursue your career in teaching, then it's a great choice to go for.

But I suggest you to complete your graduation first as minimum graduation is required to become a successful teacher. And if you want to pursue something else rather than teaching, graduation is minimum requirement for that too. Moreover, you will gain more knowledge of the subject you gonna teach through graduation.

Rest is your choice.

All the Best!!
