IPad Air update

No.

Sorry.

Your over 7-year old, 2013, 1st gen iPad Air is too old, now.

If you need/want the latest iPadOS versions with current, updated apps, then you need to seriously consider a new iPad model OR a “newer” , used iPad model capable of running the latest iPadOS 14 versions.

There are plenty of newer, older iPad models that can run the current iPadOS 14.

Sorry & Best of Luck to You!

An unit running 12.4.9 isn't capable of 13 or above; for an iPad Air, it's a first generation model.
