Gpt 4 gave me this answer, so I just wanted to check with you humans if it's correct.

Yes, there are a couple of banks in Vietnam that offer fee-free ATM withdrawals. You can use ATMs from TPBank and VPBank without incurring any withdrawal fees1. However, it’s always a good idea to double-check with your home bank to see if they have any partnerships with Vietnamese banks that might allow for fee-free or reduced-cost withdrawals.

This will be my first trip after acquiring debit cards that don't charge their ATM fees. I used to take USD and CAD there, I found rates really good, even at airports, but I'd rather not carry the same amount of cash as before, if I could get free or inexpensive withdrawals.
