I've got a very similar build to you, but still have a lot of work to do to get on your level. Mainly need to keep bulking up.

What are your stats here?

If you get fairly lean (12%ish) once and maintain that leanness, you can easily drop to single digits within a couple of months. Some people can maintain single digit bodyfat pretty easily as well naturally, depends on individual metabolism and eating habits. I reach 7-8% fairly easily by eating one meal a day at about a 500 calorie surplus for 6 training days a week, and then fasting through my rest day. 3000 calorie surplus throughout training days, and 3500 calorie deficit (maintenance around 3.5k) in the fasted window, adjusting surplus on training days if maintaining. You need to experiment to find out what works for you. I don't think getting lean is that hard up until a certain point, maintaining it is a lot harder.
