How to allow re-running of steps in GH Actions?

According to this comment, it seems like re-running should be possible:

However my actions all say “This check suite has disabled re-running inidividual check runs” and I can’t find any info on what this means (except for threads that say this is now “solved”).

There seem to be frequent issues with the first-party actions (I started another thread about that - I think they’re all connectivity issues, though this one seems less clear) which means some of my steps frequently fail, and having to re-run everything just makes it likely that another step will fail, making it difficult to get a successful run at all.
