Most popular VPNs have some form of obfuscation options in their apps. But if you're using e.g. raw Wireguard you won't be able to use their obfuscation function.
Btw technically they can't really outlaw VPNs as a whole, only commercial/"privacy" VPNs. They couldn't really tell if you're e.g. using your friend's PC as a VPN to access their LAN, since it's a residential IP. Unless they're looking for Wireguard packets, but that seems like an unlikely law since it'd piss off a lot of businesses that use VPNs to let their workers access the company intranet at home.
