You can get that control by interacting with the scheduler. Thread schedulers tend to be in the kernel and fiber schedulers tend to be in userspace, so as a practical matter, it should be easier to get that control with fibers.
But in order to get the benefits of hyperthreading you need to schedule compatible workloads on the logical pair that shares a physical core, so you need to think about scheduling groups of workloads/fibers, not individual workloads/fibers.
