Siri Search Web Images

Hello, I am trying to restrict/remove the web images option from siri search for an iPhone, but there are no options available to do so. The only options to remove for siri search are for web search content and explicit language. However, this does not restrict the ability to search up web images. Explicit web images can be found through this function, and there are currently no options available to remove this ability. Is there any way that apple can add a software update which allows the removal of all web images search through the screentime settings? Better yet, would apple be able to add the settings to remove siri search altogether (through screentime settings) so that if the user were to swipe down while in the homescreen, no search bar would appear at the top of the screen?

I have seen numerous requests across the internet for the removal of this function and I believe that it would benefit Apple long term to add this setting to help parents better porn-proof their children's iPhones. Thank you for any help you can provide.
