FLF leaves

I’ve had this for 7 months and over the summer it grew HUGE leaves compared to what it had previously. So it has smaller leaves at the bottom and bigger ones at the top. I wanted to see if there is a way to encourage the lower part of the plant to grow larger leaves or if I should just leave it. I also am wondering how I encourage it to split into a “Y” shape like a lot of larger fiddle leaf figs. No clue if any of this is possible but I’m curious!! Thanks!
