DS 7 EAT8 Unlock wheels during service?

[kirkjames1]

I'm on a trip across Europe with my 2019 DS 7 and it was time for a quick service. I know a great garage where I am now, but they specialise in Alfa Romeo / Fiat and while they do a lot of Peugeots nowadays, they are mainly manual here, so they were puzzled with the DS-7 as they could not find a service mode that unlocks the wheels with the engine off, it seems to lock them automatically. Any idea if this is this possible with an EAT8 DS 7?
