Assured Knowledge

You can procure information with confidence. Whenever you Recall Knowledge using any skill (including Bardic Lore), you can forgo rolling your check to instead receive a result of 10 + your proficiency bonus (don't apply any other bonuses, penalties, or modifiers).

As long as you are an expert in a skill, you meet the prerequisites for the Automatic Knowledge skill feat in that skill, even if you don't have Assurance in that skill.
