Hello. I am a 17 years old girl and my height is 5'3 and I want to grow 2 more inches. Can you suggest me what to do?

Unlikely to happen. At seventeen your growth centers have likely closed and you are unlikely to grow taller.If you want to know for sure an x-ray of your wrist ; hand can be analysed for bone maturity ; tell if the growth centers remain open to new growth.Good nutrition, rest and exercise allow a person to reach their tallest height while the opposite will stunt growth.
Growth. Close to the age of 17, it is most likely your growth plate has closed and you will not be able to grow anymore.
