How configure the inventory limit?

Hi, everybody.

I have a problem with inventory 7-8 and would like to know where I can set up so that I can only have up to 6 inventories.

I want to configure this on the server as well, since graphically it is not enough.

Is there a .shn where I can set the inventory limit? So that when you have 6 you can no longer use the items to add inventories.

Thank you and sorry for my bad English.

Merry Christmas!

Solution:
1. Delete the 7 and 8th Inventory Slot via NifSkope
2. Just give every Player 2 Iron Cases at the start, so players will only have 6 Inventory Slots and DON'T sell them at the npc!
