Maybe I am misunderstanding, but why can’t you wrap the inner loop in a function and use `@unroll` on that inner function? Maybe a MWE code closer to the structure you have can help…

Also this [thread](https://discourse.julialang.org/t/multiple-dispatch-with-more-than-4-methods-blocks-type-inference/49066) is useful for a similar discussion.
