Anterior tibialis - No need to target them specifically if you're doing heavy compound movements like squats and deads. But, if you do want to give them a little extra work: grab a few plates. Put one plate under your heels, and another plate on your toes, and do the oppisite of a calf press (bring your toes up while keeping your heels on the plate).
To target your peroneus (outer portion of your calves), do unilateral work like lunges, bulgarian squats, 1 leg DLs, etc.
