Help! Foundation years and

Hi!
I am a mature student/career changer. I was unable to complete my access course with just one module remaining due to life circumstances, but have had my heart set on studying a particular course at Kent for a while. I have an offer which I now can't meet. They don't offer a foundation year option on this course either.
I was homeschooled and didn't get formal qualifications barring an administrative apprenticeship a long time ago. I have ten+ years of work experience and have spent the last few years building out my resume in my new career (ecology & conservation) with a few different ongoing voluntary experiences and a 6 month stint at a well known charity, and a curated online presence in the industry. Do I try my luck and reapply through clearing without formal qualifications as a mature student? Do I apply for a related course with a foundation year and switch at the end of the foundation year? Or go for a different uni with a foundation year whose course structure doesn't appear as strong? I don't even know if I stand a chance at getting in anywhere, but I'm finally after a few years in a position where I can make uni work as a mature student and career changer, and I desperately want to give it my best shot.
Any advice would be so helpful! Thank you!
