Is your feature request related to a problem? Please describe.
As much as I like this mod, the backpack models often stick out and interfere with elytras, capes, and any visual that goes on the back. People who like minimalistic looks also sometimes wish they could disable the visual.

Describe the solution you'd like
I would like the option to disable the visual of the backpack.

I'll add config option to disable all backpack renderings for player. It means that neither you nor anyone will have visible backpack from your client if option is set to true. Does it satisfy you?

Actually there's option to disable backpack already in config..
In Client configuration - disableBackpackRender

So it would hide the backpack for you and all players that see you? Or only for you, how you see this feature

Either works to be honest. I think that if doable, it should hide for everyone. Possibly have rendering backpacks be in the config?
