I Can't Disable Safe Search on Google or Bing. Can Anybody Help?

I hate to ask this as I have always considered myself technically skilled (I used to have Microsoft MCSE qualifications many years ago) but I cannot seem to disable Safe Search on Google or Bing on my laptop. I am in the UK, I use BT as my ISP and my computers are all Running Windows 10 and/or Windows 11.

Bing it tells me "Your country or region requires a strict Bing SafeSearch setting, which filters out results that might return adult content. If you're seeing adult content, tell us about it so we can filter it in the future. To learn more about SafeSearch requirements in your country or region, see How Bing delivers search results."

Google tells me "You don't have permission to turn SafeSearch off. It's locked by the device or network that you are browsing on."

I figured it out. The browsers were all signed into my profile, when I tried a different browser that wasn't linked to a profile it worked fine. if I signed out of the browsers they then worked.

Looks like a lot of this is down to restrictions in the UK. I cannot use Google or Bing to search for risquรฉ content so I have switched to DuckDuckGo which doesn't have those restrictions.
