PVE standards for mixed servers

So I like the idea of the PVP standards that are placeable in PVE servers but I would like to have a PVE standard that can only be placed by admins to declare a place/building PVE so that it cannot be damaged it would make admin bases safe from raidings or if you want to have a mixed pve and pvp server it would help reduce the griffing a bit. Make it so that they can be placed by admin only and removed by admin too???

I don’t know if it’s possible but it could help my server having people of both varieties playing together making pvp pve and pvec possible on same server. Good idea
