F5 SSL Client facing server using HTTP only. Is this possible to use only F5 for Client Cert then translates the port to http facing the server?

very cool and page is loading using https:// offloading on f5 however there is an error. page loads different looks like CSS issue but when you check the cert it says "Your connection to website.com is encrypted with 128-bit encryption. However, this page includes other resources which are not secure. These resources can be viewed by others while in transit, and can be modified by an attacker to change the look of the page. Is there a way to bypass these remarks on clients side by not clicking allow or exempt?
