Can’t block websites and internet

[0mni]

I can’t block websites and internet access at the same time. If I block sites then I can’t block internet access and vice versa.  My router model # is: fios-g110.  

Using OpenDNS to block sites is not an option since they can still be accessed with a VPN. 

I’ve tried programs  that block sites and require a master key to delete, but the blocks can be evaded simply by downloading different browsers. I’m using Windows 11. 

Anyone know of a way to block both internet access at a certain time on specific devices and websites with my router or a program that blocks sites without a way to evade blocks  with other browsers? Thanks and appreciate it!
