No. Trump has emboldened the anti-Cuba sentiment among the Right, and they will stick with that as long as he is President.
Wasn't it actually emboldened by Obama initiating a thaw in relations with Cuba? Since Obama was for it, wavering Republicans were against it, simply by virtue of being reflexively anti-Obama.
If Trump himself ends up supporting some kind of softening of either the trade embargo or the travel ban or both, then enough Republicans would follow him that it could pass Congress. Not that I'm expecting him to do that any time soon, but could he do it at some point during his presidency? It may not be likely, but I wouldn't rule it out. Trump is pretty unpredictable.
