[ 1.12.2 ] How do I change the player inventory layout?

As the title suggests, I am looking for ways to change the image (layout) of the player inventory.  I am amateur but I would like to try it. (Please understand my terrible English)

Once in the player inventory, I want to leave only 9 hot bars, a player render, and Armor render. I would also like to include information such as health and food. ( Number 1 in the picture below )

Here is a concrete image created in this way. 

Can you help me please? I use version 1.12.2.
