I don’t think so, you can read explanation made by Tim Lincoln here:
https://answers.unrealengine.com/questions/98206/missing-support-for-uint32-int64-uint64.html
If you really want to use a int64 with Blueprint, simply made a wrapper like this plugin : GitHub - Daekesh/KeshUE4FundamentalTypeWrapperPlugin: Wraps all the UE4 C++ fundamental types (int8, uint64, etc.) into BP-accessible structs.
I hope this help you !
