Can I do internship after exmatriculated? 16b to 16e or 17a

Hello,
I exmatriculated due failed exams.(had medical problems for 2 years, did not get any absence of leaving etc. completely my fault. Taking responsibility.) But now I found internship. I emailed auslenderbehorde but they did not answer me. Is it possible to change 16b to 16e or 17a or any other interships visas while I am still in Germany?
Thank you
