UK TV detects VPN. Make VPN undetectable

Hello. First of all, I would like to state that if you do not know these things well, please do not bid. VPN was installed on the virtual server in UK for the itv.com site, which is only accessible in the UK. But the site detects that we are connected with VPN. It is necessary to configure the VPN so that it cannot be detected. We have OpenVPN and Wireguard servers. We can do it on whichever is possible.
