Hello,

There is no option from settings. You can add following to `assets/custom/custom.css`

```css
.bcimg, .qrimg {
display: none;
}
```
The above file is for SMA only for sales, quotations and purchases. You might need to add the above code to `assets/custom/pos.css` & `assets/custom/shop.css` to hide them in receipts and shop order views.
