+===== Disabling systemd-resolved =====
+//This was actually tried with success on a //Linux Mint 20 Ulyana//, but I assume it works pretty much the same on //Debian// and all its derivatives//
+The most easy way would be to uninstall //systemd-resolved//, but as it is bundled with //systemd// which unfortunately is a crucial part of //Debian// meanwhile, this ist not possible.
+<code bash>
+apt install resolveconf
+systemctl disable systemd-resolved
+vi /etc/NetworkManager/conf.d/10-dns-resolved.conf
+</code>
+We need to override ''/usr/lib/NetworkManager/conf.d/10-dns-resolved.conf'', therefore the file name does not really match its purpose((Actually, you should adapt the name, if the respective file in ''/usr/lib/NetworkManager/conf.d/'' has a different name)):
+<code plain /etc/NetworkManager/conf.d/10-dns-resolved.conf>
+dns=default
+rc-manager=resolvconf
+systemd-resolved=false
+</code>
+Disabling //systemd-resolved// in //systemd// and in //NetworkManager// propably doesn't make much of a difference after your told //NetworkManager// not to route DNS queries to it but for saving system resources.
