Materials Checklist
Craft the Calyrex Ice Rider Radar to locate the Crown Spire.

You should be able to find the Crown Spire in a Snowy Plains biome

Before entering the spire, take a look to the right of the building. The back right ice spire has a hidden barrel. Walk up to it, find the warped fungus, and break this ice block that's facing it. You should find the barrel with the Calyrex Crown in it.
Continuing around the spire, you should see a carrot patch. One of them will be blue, and is actually an Iceroot Carrot. Break this and walk over to the composters and spruce trapdoors. Throw the carrot on top of the composters. The ice peak behind the composters will open up and Glastrier will spawn there.
Search the barrels, books, and Poké Dolls for loot, including Tera Shards. Climb the ladders to the top and place the Calyrex Crown on the Calyrex Statue to summon Calyrex.
Once you have both Calyrex and Glastrier, send out Glastrier and use the Reins of Unity on it. The Reins will become charged. Use the charged Reins on Calyrex to form Ice Rider Calyrex.
