I'm a first time TP-Link Mesh Router customer (I've used some of their other Routers and products as well) and I stumbled onto this forum looking to find out if the new XE75 Deco Mesh kit I just bought supported secure DNS.  

I am highly network technology savvy and I've setup countless routers for clients over decades as well as dozens of my own that I've administrated and customized for my home network.

I am baffled that a company making router products in the year 2024 would not provide secure DNS as an included option.  I totally understand that the average unsavvy home network user probably isn't looking for or demanding this option, but there are many knowledgeable IT guys such as myself who know to look for it and how to use it, and I think it's inexcusable for TP-Link not to provide it.  
 

This has led to me question my purchase of the Deco kit and I now have to consider looking at alternative options for personal use and what I recommend to friends, family, and clients.
 

I'll likely solve this for myself by setting up a local DNS server that can make the requests securely on behalf of the router, but I shouldn't have to do that and my clients and loved ones definitely aren't going to know how to do that, nor should they have to.  I'm thoroughly disappointed!

  @Kevin_Z please add ax73 support for DOH.

  @Kevin_Z I bought two Archer BE550 (non pro versions) to replace my old ASUS AiMesh system at home. They work ok, but I did not expect that DoT/DoH are not supported there. That's a shame. My old device from ASUS supports that feature. Really hope you'll release that feature for BE550.
