https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+            NixOps autoLuks is deprecated. The feature was never widely used and the maintenance did outgrow the benefit.
+            If you still want to use the module:
+              a) Please raise your voice in the issue tracking usage of the module:
+                 https://github.com/NixOS/nixpkgs/issues/62211
+              b) make sure you set the `_netdev` option for each of the file
+                 systems referring to block devices provided by the autoLuks module.
+
+                 ⚠️ If you do not set the option your system will not boot anymore! ⚠️

+                  }
+
+              b) set the option >nixops.enableDeprecatedAutoLuks = true< to remove this error.
