Read this article for more details: Accessing 32-bit DLLs from 64-bit code

Definitely a possibility but using COM to do the proxy mechanisme with a 32-bit DLL from a 64-bit process feels a lot like using a tank to go do your groceries. Certainly possible but not easy, and that is aside from finding a parking spot in the neighborhood of the supermarket.
If you have the source code of the DLL, recompiling it for 64-bit, even if that requires modifications to the source code to make it fully 64-bit compatible is certainly a lot easier.
And if you don't have the source code, it may be definitely time to search for an alternative of that old DLL to stay compatible with future developments or abstain from using LabVIEW NXG at this stage.
