Wow. Do they block VPNs inside your country too?

Anyway, there's openvpn and there's nebula (I think nebula doesn't use wireguard.. do double-check), or you look into things built specifically to hide traffic (keyword: "vpn obfuscation").

No idea if VPN protocols other than wireguard may be blocked too (probably?).
No idea if trying too hard to circumvent government policies may get you added to some list you'd rather not be in.
