Hi, not to worry, there are plenty of things to do that don't include drinking or clubbing during freshers week. Freshers week actually consists of a lot of freebie fairs (my favourite thing!), free dominos pizza at the freebie fairs, there will be society fairs, sports fairs, the students union will hold a lot of events, in person or online, games you can participate in, with prizes usually being some university merch! These are a lot of fun, definitely get involved inn them. The events run by the students union are also a good way to meet your students union officers.
A good thing to do is to invite/go with flat mates to these events, to the freebie fairs etc. It's a good way to get to know each other and have fun in a non-alcoholic environment without any potential awkwardness.
When freshers week is approaching, look online for your universities freshers week, they should have a list of events lined up, so you can see in advance which ones you want to go to and plan accordingly! Societies will also be hosting taster sessions, these are a lot of fun to get involved in, meet new people, and find societies you want to join long term.
I hope you have a fantastic freshers week, and that this alleviates some of your worries
