How old is the bunny?
Many rabbits mellow with neutering + age.
They also need stuff to do, which could include having cardboard-boxes and twigs/branches of safe trees (apple, willow, hazel + many more) to chew on. Bored rabbits tend to chew their wire cages, esp if the cage is small and offers few other possibilities for activity. It’s extremely common and one of the reasons why rabbits shouldn’t be kept in small cages.
Some rabbits like to be held. F ex my mother has my Bam in her lap just now and Bam is just sitting there, apparently enjoying the cuddling. It did take like 1,5 years before he accepted proximity of this type though, bunnies can be extremely “slow learners” – as Brian says, they are prey animals and trust is not their first instinct so to speak. Maybe your bunny just recently has come out of extreme fear of his new environment. For a bunny, a little less than 2 months is a very short time, that’s my experience at least. Be patient, he may very well become cuddly if you keep treating him well!
