If they really wanted to, I could see currency adjust becoming a thing. Similar to tip adjust, it'd basically be a USD or [currency] checkbox you'd check on the paper receipt (which gets entered by the server later). Unfortunately, this would mean that the exchange rate from the time you were at the restaurant to the time the choice actually got run could vary significantly.

In the case of DCC post PIN entry, there may be limited recourse if DCC gets accepted.
On the other hand, if DCC post-PIN entry is that common, I could see issuers still accepting chargebacks for that since the PIN entry was for the pre-DCC amount, not the post-DCC one.
