Isnt it a server setting? How should it not be possible 
But at least someone got an answer… Because all I get is, “wrong section”
Answer (wrong section): Thralls reverted to naked status, low HP, no gear issue - Information thread
No answer(right section): PS4 Patch (08.10.2019) - The Wine Cellar, new animations, Debaucheries of Derketo and more!
Also the person asked wrong… No one watns to disable PvP. But the raid-time and purges and thats for sure a setting at the servers…
So yeah, Hugo is for sure right. Funcom cannot disable PvP. But they should just disable raid-time and purges… Not deactivating a whole gaming-mode.
