How to disable internet but remain connected to LAN network?

Question

I have a windows computer that I want to isolate from the internet. I need this computer to remain in contact with other devices on the network and be able to VNC into it.

I saw some solutions saying to change the default gateway / DNS but this doesn't actually isolate the PC from the internet.

I was thinking there could be a way to do this with windows firewall but I'm not an expert. Tried searching online and couldn't find an easy answer!

Thanks!

Change its default gateway to one that does not route to the Internet.

Usually this would be implemented with a VLAN. Take care to not let its router discover paths to your Internet gateway.
