Yes it's possible
@Tenac. If you search for any of my posts on this including earlier in this thread, you'll see I have adapted the NATO socket to a SB50 Anderson which connects to a DC-DC charger in my camper.
By default the NATO socket either does not work unless you have the front winch option, possibly only an MY23 ROW quirk; or it does work but only if certain operating conditions are met including speed below xx mph. That makes sense when you recall that IA supplied the NATO socket for use with the removable rear winch which is not typically used while blasting down the freeway.
If you want to make the NATO socket available at other times for other purposes (look away now Ineos), you will need to take over control of the circuit that supplies the trigger coil on the Albright Solenoid located under the right side trim panel in the rear.
Options:
1. If you want the NATO socket live when the key is on/engine running you need to run an ignition feed to the pull-in side of the solenoid coil.
2. If you want the NATO socket live anytime via an ON/OFF switch you need to run a +12V feed to the same spot. The solenoid uses power to operate and this will add to the battery drain if you leave it turned ON without the engine running even if there is nothing plugged into the NATO socket.
If you do this I also recommend derating the NATO supply circuit fuse from 350A to something closer to your expected maximum current draw. I'm using a 60A fuse I robbed from the 7-way fuse holder (ROW vehicles) because I also use the NATO socket for my portable compressor.
No point sacrificing your equipment to protect a fuse that's bigger than you need
I have no experience with 48v trailers but the above will get you 25% closer
