Lol ok so
I swim sometimes for fun. That makes me an aquatic species, am I right?
Young dumeril's do climb sometimes- that's known. Just like MANY young terrestrial species. Once your dum gets older and bigger, they stop climbing altogether. I've removed my branch from my dum's enclosure once she was around 3 years old, because she just burrows under it and never uses it.
And regarding your setup- Where are the hides? Where is your thick substrate? Your setup is honestly terrible for a dumeril's. Dumeril's need hiding places and they are a BURROWING species, not even just a terrestrial species. If you provide them with substrate at least 3" thick, they'll burrow way under and have their nose poking out.
Your substrate is so thin, and your setup is so open.
Tip: Bad setups ALWAYS make snakes behave out of the norm, usually out of discomfort and seeking somewhere better.
