Hello Aspirant,
Yes, you can obtain a diploma after Class 10 even if you did not pass Class 12. There are many polytechnic institutes that offer diploma courses based on Class 10 marks. A 2 year gap is not usually a major problem as long as you can explain it sincerely--whether you prepared for exams, not had any exams, or explored career options. When applying for higher education or jobs, focus on what you learned and how you developed during that time--be honest and confident in your journey--there are many ways to your goals.
