Uni accommodations without DSA?

I start uni in September but I was only diagnosed as autistic last month (and I still haven’t received the full report). I’ve started filling out questionnaires for the disability team at my university, but I haven’t applied for DSA. Will this limit the accommodations I could be offered? For example, I struggle during seminars or group work because I get quite overwhelmed with the amount of people talking and all the different things I have to process, so being given extra information or told things in advance could help. Would this be something my university could help with without me applying for DSA? I know that some things like special software that records audio and sorts notes would probably not be available without DSA, but I don’t know what else I wouldn’t be able to have access to. Is this something I should just talk to my uni about when I start??
