Be sure to follow the rule before you head out.

It's exceedingly easy. Would just need to change the router password if that's feasible.

Or, grab a raspberry pi and install Pihole, then change the router to point to that DNS server. You can block websites that way and put the Raspberry Pi where your dad can't find it. He'll have no idea why he can't get to those sites.
you could also point it to 127.0.0.1 in his hosts file
