Looks like this is what you're looking for https://docs.rs/bevy/latest/bevy/ecs/system/struct.Query.html#method.iter_combinations_mut

this wont work as mutable and immutable access to the same data will cause a conflict. You will need to iterate over a single mutable query instead of two. A common pattern would be to iterate over it immutably first, collecting matching entities into a vec and then using that vec to iter the query again
