All Anglosphere countries (US, UK, CA, AU & NZ) have jury duty which is mandatory for both neurodivergent and neurotypicals when they’re given a summons. I mean, Autism is considered a legitimate excuse (if you assert how the condition is hindering civic duty, since saying Autism on its own is a hit or miss & won’t guarantee an immediate excusal or whether the judge will believe you despite them being the arbiter).
That is, if you’re called on the panel facing the lawyers at mercy if they’ll pick you as a juror or be dismissed. You can plead your case if you’re selected and refuse to serve (granted that you present medical proof or psychological assessment mentioning Autism). Jury duty is something both neurodivergent and neurotypicals end up on the same boat as it’s mandatory for them to show up in court otherwise they’ll be fined or jailed.
If it’s something like you need a break every so often, be upfront about it, “I’m autistic and need a defined break every hour to stay engaged” or similar might be enough to get you tossed from the pool, but it’s not permanent. I assume most lawyers/judges will not want so many breaks, as that draws out the process and can kill flow.
Aside from that, in the USA, there is both federal and state level jury duty, so even if you find the magic form for your state to pull yourself from the list, you may still get called for federal jury duty.
