Transferring from Stern to Stanford, MIT

I was recently accepted into stern as undecided but I am worried I will not want to pursue a career in business what is the chance I can transfer after my freshman year to a school such as Stanford or MIT. Assuming i could maintain a high GPA freshman year. And if not these schools which.

GPA: 3.98 UW/4.24W
9 APs/Advanced classes
Average ECs (Kinda weak honestly)
