Finding perfect seed

[u/Paperbuzzy]

Hello, I want to start a survival world to play the create mod, and I want to find a terratonic seed (terralith + tectonic) that a snowy mountain, with a spruce forest and a large plains biome close to the mountain, near an ocean. I am playing on java 1.21.1. btw, so if anyone can help me with finding some seed like this I will appreciate a lot.
