Can you hide Tor from ISP?
Yes, the Tor browser hides activities from ISPs. However, VPNs encrypt traffic before it even reaches your ISP. So while Tor may make it more difficult for your ISP to see what you're doing online, a VPN will make it impossible.
Can my ISP know if I use Tor?
Your Internet service provider (ISP) and local network can see that you connect to the Tor network. They still cannot know what sites you visit. To hide that you connect to Tor, you can use a Tor bridge.
