Mikrotik DoH user here. While I don't use Quad9, I do use 1.1.1.1. I hope they don't follow suit before Mikrotik get a chance to add HTTP/2 support (if ever).

You should look into dnscrypt[0][1]. Easy and lots of options. jedisct1, cofyc, and many others have done a great job over the last decade here.
