If your snake prefers that spot to the other hides, I'd improve on the other hides instead of taking away the spot he likes. The other hides could also be fine if you add more foliage or stones or something as cover at the entrances.
But since he's brand new, is maybe stuff a paper towel in the large openings, but otherwise don't bother him. He might also just need some time to figure out what his hiding options are in his new place.
