Rematched without PD approval

So I’m a categorical PGY-1 who recently reapplied through the match and matched into a different specialty without approval or a letter from my PD. I plan to finish out the year and then resign. I have not signed a contract for a PGY-2 year with my original program. I get I should of told my PD from the start I was not happy and wanted to switch specialties. I am having a meeting with my PD this week. I was just curious if there’s anything my PD could do to block me from going to my new program?
