Funding for a new course

So, I started uni doing a foundation year for a maths degree... which I failed. I then moved to a different uni to do computer science, finished my first year and moved into second year... which I failed.

Since leaving university, I have been diagnosed with autism and ADHD. Obviously, not understanding or getting support with both of those explain why I had so much trouble with uni. I have started meds for my ADHD though and things seem to be going quite well.

I am reasonably sure that if I submitted compelling personal reasons in order to get one additional year of funding to finish the last two years of my computer science course, I would be awarded it (maybe I'm wrong here... please feel free to correct me)

However, I am a very different person than the one I was when I was first applying for university. My life goals and interests have changed drastically and while I feel like I am now in a place to achieve a degree and that it would benefit me in the long run, I don't want it to be in computer science.

What I would be aiming for is two or three years extra funding in order to go back to uni to pursue a different subject.

I appreciate that no SFW staff could give me a definitive answer on whether this is possible without me actually submitting my CPR, but if anyone could tell me if it's even worth the work needed to do that, or if anyone has been in a similar situation, any advice would be massively appreciated.
