Can't turn the sky off?

[Sotaris]

I did some searching and found a thread from 2019 where someone was asking about this as well, but there was no good answer as to why that person's option to turn the sky off wasn't there as well.

they were told from people here that there should be an option on the top right of the display section of alt+o options to turn sky from simple to complex to off. And that's exactly how I remember it back in the day as well.

I however don't have this option? Was it removed from p99 for some reason, or what can I do to disable it? It's just how I played back in the day and I love the black sky from it.

Thanks!
