Combine water, oats, almond milk, brown sugar, cinnamon, nutmeg, ginger, and cloves in a multi-functional pressure cooker (such as Instant Pot(R)). Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 10 minutes. Allow 10 to 15 minutes for pressure to build.
Let pressure release naturally for 10 minutes. Finish releasing pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid. Stir with a silicone spatula until oats are combined and thick.
