[Parental Control not blocking HTTPS websites]

I've set Kaspersky Parental Control to block every website except for a few exclusions. I've discovered that it's not working because it is only able to block HTTP websites and not HTTPS. How can I fix this? Kaspersky Internet Security 19.0.0.1088 Windows 10 64-bit Ethernet connection

[How can I block any URL containing any the following words: nsfw, proxy, porn, and xxx?]

Some pages contain the word proxy in them and can be used to get to porn sites. I want to block any URL containing any the following words: nsfw, proxy, porn, and xxx. I am using parental control on Kaspersky Internet Security 2018.
