Via ChatGPT 4 (accuracy unverified):

Yes, you can configure systemd-resolved to use the DNS servers in the order provided without dynamically switching based on speed. Here’s how you can do it:

1. Edit the resolved configuration file:

   Open the resolved.conf file in a text editor:

   sudo nano /etc/systemd/resolved.conf
   

2. Modify or add the following line:

   DNS=`IP_of_pihole` `IP_of_mikrotik`
   DNSStubListener=no
   FallbackDNS=
   

   Replace IP_of_pihole and IP_of_mikrotik with your actual DNS IP addresses. This tells systemd-resolved to only use the DNS servers in the order you've specified.

3. Prevent automatic DNS changes by network manager:

   If you're using NetworkManager, create a drop-in configuration to prevent it from overriding DNS settings:

   sudo mkdir -p /etc/NetworkManager/conf.d/
   sudo nano /etc/NetworkManager/conf.d/dns.conf
   

   Add the following content:

   [main]
   dns=none
   

4. Restart services:

   After making these changes, restart systemd-resolved and NetworkManager:

   sudo systemctl restart systemd-resolved
   sudo systemctl restart NetworkManager
   

This should ensure that your system uses the DNS servers in the order provided without any automatic switching.
