Sorry for misunderstand. It does went missing. Hope they'll add it back soon.I understand that UI changed.
You are describing DNS Server. No issues there.
Specifically, DNS Privacy Protocol > DNS-over-TLS Server (DoT).
When it's enabled, Preset servers option is missing as in my included link for an image from
RMerlin thread here https://www.snbforums.com/threads/preview-asuswrt-merlin-384-11-with-dns-over-tls.56095/.
Selecting those presets would populate DNS-over-TLS Server List (Max Limit : 8)

Internet Connection.png – is how it looks like right now, that list I had to populate manually. And Preset servers option is missing.
RMerlin DOT-preview2.png – shows Preset servers, how they were in previous version 3.0.0.4.388.23110
I understand it can be a bit confusing.
DNS and DNS-over-TLS
You'll get different test results at https://1.1.1.1/help
if i remembered correctly, the preset doesn't include 1.1.1.2/security.cloudflare-dns.com. That is why i set it manually and not realize it went missing
