Interviewing At Other Amazon Offices After Accepting Amazon Offer - Acceptable or Not?

My question is as the title states. I have accepted an offer for an SDE1 role at Amazon in North America which would commence later this year. Is it acceptable to interview at other Amazon locations given they're the ones reaching out to me to organize the interview? A little background on the preceding events - In early fall of 2019, I had applied to numerous positions with Amazon around the world. It appears that North American positions use a different portal than European/African positions, with North American positions using the "amazonuniversity.jobs" portal and European/African positions using "amazon.jobs" portal. I should clarify that all applications that appear on one do not appear on the other. My initial intent was to interview with a few offices to have a baseline of what to expect and ideally pick which one served as the best fit (if I were to have been fortunate enough to received multiple offers). Unfortunately, I was hitting the on-site interview stage around the holidays which ended up leading to delays and rescheduling. I'm now being reached out to by many of these positions (either for the first time or to reschedule) to set up on-site interviews. Is it wrong to pursue these? I mean, my thought is that it is wrong, which is why I am seeking opinions on the matter as any who I have consulted have told me to pursue these interviews. Appreciate your time!
