I need a webpage filter

This is a bit of an odd question I bet.

I’ll save you the hassle of the story but I need a way to block all websites related to gambling, proxy and VPN.

The network just consists of a laptop and a router, laptop is not mine but I have full admin rights to the router. Is there anything I can do besides contact my provider? I need this in place.

I am with EE and use the standard router they send out.
