Answer 1

In the Sinnoh-based games, although the Azure Flute can potentially be the first item the player obtains in Brilliant Diamond and Shining Pearl, the player must enter the Hall of Fame and also obtain the National Pokédex to be able to use it.

When the player reaches the Spear Pillar at the top of Mt. Coronet and steps one tile north from the entrance, they will be prompted to use the flute, which will play a unique and eerie tune and reload the Spear Pillar map with a steep staircase that leads to the Hall of Origin. After it is used and once Arceus is caught, the Azure Flute will no longer trigger the entrance to the Hall of Origin when played at the Spear Pillar and the message "The Azure Flute echoed hollowly..." will appear. Should the player knock out Arceus, then the Azure Flute can be used to summon Arceus again.

Tldr: After beating the Pokemon League and obtaining the National Dex, go to Spear Pillar, where you'll be prompted to play the flute after you take 1 step forward. When you play the flute, a
staircase will appear. Go up it to catch Arceus.

Answer 2

You can get Arceus actually! If you head to the top of Spear Tower (where you encountered Dialga/Palkia) and use the Azure Flute, a staircase leading to an Arceus encounter will appear.
