Can I Un-enroll and enroll at another university

Hi all, I've been stressed about this recently because I'm unsure and didn't notice until recently.

I did my first year at Leeds Beckett University, and I then applied for a 2nd year start at Birmingham City University. I've only just seen on my course timetable they gave me a place in First Year. I've already enrolled at BCU now, with SFE too.

However, I also still have my accounts and the enrollment link from Leeds Beckett University. Would it be possible for me to Withdraw from BCU and instead enroll at LBU?
I know it's my fault for not reading properly, I was under a lot of stress. Is there anything I can do here?
