Ok, not trying to be a buzzkill, but it is strongly advised to not handle your new snake for a little while as it acclimates to its new enclosure.
I personally suggest waiting until the animal has eaten 3 consecutive meals without refusal prior to handling.
Getting the snake eating regularly is important, as Bps can be finicky eaters. Stress and poor husbandry are the main causes that a snake will refuse food.
I know it's tempting to hang out with your new pet, believe me, I get it. I just added a new snake two days ago and it's already killing me, hahahaha. But think if it this way, the animals health is most important. And you'll have plenty of time to handle your snake once it is eating, 25 years or more...
Sorry to be a buzzkill, I just want your new pet to work out well for both of you.
