Using existing dlc content from GTA V

We found a server which enables the Cayo Perico map but doesn’t stream the files and just uses the locally available map and assets and realises enabling it is done as outlined here Enabling the island on build 2189

What I’m wondering though is if it’s possible to enable other dlc lack levels to be included without streaming, such as the Diamond Casino. Those assets are available in that if I open Code Walker and switch the dlc pack level it shows up. I tried using a streamed diamond casino from a reknowned author who makes “no lag” map add ons but we have major issues streaming, and that’s on a top end Ryzen based dedicated server.

Can these dlc pack levels be enabled easily without needing to stream?

2189 includes all versions prior, as well.

Legend! I just loaded up with our streamed versions disabled and it’s there.
One further question though, I remember seeing holes in the FIB building when we first set our servere up. which was xied with bob74_ipl. Is there a known way to fill the holes on diamond?
