Issue zero trust

I am using Zero Trust via 1.1.1.1 warp app and notice that it doesn’t connect to warp+ and it says connect to warp and it says

tls=TLSv1.3
sni=plaintext
warp=on
gateway=on

and how can I eanble WARP and notice that I did not setup up gateway doh subdomain so that protocol is locked to HTTPS instant of WARP. in terms DNS OVER WARP is much faster and secure than DNS OVER HTTPS. so how can I disable gateway doh subdomain and enable DNS OVER WARP

thanks
