How to adjust breastfeeding schedule?

Hi everyone! So by the end of the month, I plan on going back to work. I just wanted to know how can I adjust my son’s breastfeeding schedule? By the week I go back, my son will be 10 weeks. I do plan on changing my schedules to 4-4.5 hours per day (4 days max) as I’m going to school, working, and making time for my baby. I only plan on working 6p-1030p at night, and I’ve been tracking his sleep since he’s been born. I know sleep schedules tend to change over time so I was wondering how other moms have done it? He does tend to take his naps around the time I plan on working. I’m exclusively breastfeeding at the moment, but I’m okay with supplementing a bottle or two if he does wake up or is more hungry when I’m gone. He’s essentially feeding every 3-4 hours and does sleep through the night (12am-5am). Thank you in advance!!
