Can I change the backpack icons?

I have no script, but can I change how the icons look on the backpack when in game? Is there any script to do that?

Hello there @vtrustmea, sadly you cannot customize the roblox's backpack system's icon, but there is another theory,

you can make or find a custom backpack system, then disable the standard roblox backpack system by typing this in a local script.

game:GetService('StarterGui'):SetCoreGuiEnabled('Backpack', false)

Hope this helped!
