How to prevent Steam Achievements?

[LumiMakesStuff]

I often play lots of GDPSs so I was wondering if anyone knows how to prevent achievements from being awarded on Steam!

I already have Server API setup so it won't disable them on GD's servers!
I don't have Discord, so I apologise in advance if anyone has asked this before there!

for some reason i can't mark it as the answer tho >-<
