I have not tried shucking drives but I imagine they should work. Currently have 20tb Seagate ironwolf ST20000NT001. The script takes two seconds to run and needs to be redone everytime you update the Synology software which doesn’t seem to be overly frequent. Running the script or not you have the same full functionality. Script just removes the warnings.
I think the best you can do is use pihole with unbound so all dns requests go directly to root servers so no middle man involved. If you have a raspberry pi and use dietpi it is very easy to setup.
