Software engineering without maths or compsci a level

I am in year 13 and have always regretted the a levels I chose which are French Economics and Product Design, I wish I'd chosen maths and compsci instead of French and design because I've always loved coding. I did not apply to university this year and will be applying in September this year. I have absolutely no idea what I want to do other than computer science which I think I'd enjoy and be good at which seems impossible without maths or compsci a level.
One option I have looked at is doing a 1 year computing conversion course at the end of a bachelors degree but it seems like the bachelors degree would be such a waste of money and time.
Alternatively there are boot camps and online courses which I could further teach myself to code with but I am unsure how much value they would add to my CV and if an employer would actually hire someone to be a software engineer without a compsci degree.
Additionally if I were to do a bachelors degree in a different subject any suggestions for what could be useful or relevant down the line, maybe accounting and finance for fintech?
I appreciate my a level choices really aren't ideal and it is probably quite unlikely I end up as a software engineer but I just honestly feel so lost and uncertain right now and any advice or guidance would be massively appreciated. Thank you in advance.
