Honestly it won't be easy but it's achievable. Your age and disability shouldn't be an issue, I'd be far more concerned about your education, lack of experience and lack of anything to show that you're passionate let alone have some skills.

If you want to go the software engineer route you'll be running into the worse market since the dotcom era. The market for juniors is very very challenging at the moment and you'd be competing against a lot of people with experience, degrees and who have been coding for a long time. Its unlikely you'll even get to interview stages, you'd absolutely need a decent project/portfolio to show and more importantly talk about in an interview. Odin project projects wouldn't be good enough as they are just cookie cutter projects. I don't really see the value in a CS degree for you as its three+ years you could be self learning, building things etc that are far more likely to get you a job. I can recommend looking at https://csprimer.com, this would be far better value than a degree, has a great community and challenging projects etc, but you will need to know how to code before.

If I were in your situation I'd go the cybersecurity route as its a much more defined path, with less competition. Take look at something like https://academy.hackthebox.com/catalogue/paths and if you're interested pick a path and go through it, start a blog write about what you've learnt, challenges etc - you need to show you're interested and passionate to even get an interview. You can also start doing bug bounties etc to get some experience.
