Hide some unuseful options

Hello Dear Managers

how i hide all these options in sales invoice see the attach imageddd

Some cannot be hidden, because they are available for all invoices, whether you use them or not. At some point, you might decide to. An example is the Discount option.

Others appear only when the relevant tab is enabled. For example, if you have no custom themes, the Custom theme option does not appear.

Because some are often not used, they are at the bottom of the screen, out of the way.
