Not really
An 2012, iPad 4th gen will be 9-years old by this Sept. 2021.
All support for this iPad ended 2-3 years, ago.
It's 2021 now!
Time to seriously consider a purchase of a new iPad model OR a much, MUCH “newer” and less expensive, refurbished or used iPad models, from better known, trusted Apple product/device retailers/resellers, locally or online, on the Web/Internet, capable of running the latest iPadOS versions.
There are PLENTY of newer, older iPad models that can run the latest, current versions of iPadOS.
I am sorry that you had to learn this, but this does not change any of the facts regarding these very old iOS devices.
Sorry & Best of Luck to You!
