Dayz server self host for ps4?

Hello there's ps4 dayz server and wanted to know because there are also modded ones and my questions are

1 how to host a dayz server for ps4

2 how to mod the (programmed and in which programming language)

3 do you know good dayz rp servers for ps4?

DayZ PS4 servers are rented because there are no public server files.

DayZ servers are script servers, this is not an official language, but DayZ specific.

I don't play on the PS4, so I don't know any servers (apart from my own, but it runs for and on the PC)
