Can I fix my uneven lips without plastic surgery? I was born with cleft palate and have had all the surgeries (photos)

I was born with a cleft palate, and i had all the surgeries, I am 18 now and I'm so soo insecure (2020), the only surgery left is the septum deviation one which I will have it next year, but can I do something to fix my lips without any other plastic surgery?
