LF Undetectable proxy/vpn/vps help

Not sure where to post this so I'll just post it here.

I'm not very experienced in this but I'm looking for an UNDETECTABLE static proxy/VPN/VPS to access certain sites. Is there even such a thing or will everything be detected by modern detection technologies? Would VPN be better than proxy? Why?

Also I'm currently connecting to the proxy by editing proxy settings in chrome, would that make a difference in detectability?

Any input is greatly appreciated.
