The ethtool command is provided by a package named ethtool  which you can install on Deepin,too.
Unluckily Deepin doesn't provide an online package index so I can't find out if it is in the official repositories.
I found it here for Arch,but that will only help you if you want to compile it yourself:
https://www.archlinux.de/?page=P ... _64;pkgname=ethtool
You can simply try "apt-get install ethtool" first,hopefully it is in the repositories.
If not,you could add Debian repositories if it is in there what I don't know too.

Thx, but that was something I alredy knew


The trick was to run the script as a systemd service
Here is how:
Make sure your script (I named mine eee_off) is executable and the first line (the shebang) is #!/bin/sh.
=====================
#!/bin/sh
sudo ethtool --set-eee enp0s31f6 eee off
=====================
Place the script where you want (in my case it was /usr/bin/)

Then create the .service file in /etc/systemd/system (a plain text file, let's call it eee_off.service):
=====================
[Unit]
Description=Turn off EEE on interface

[Service]
Type=oneshot
ExecStart=/usr/bin/eee_off

[Install]
WantedBy=multi-user.target
=====================

Once you're done with the files, enable the service:
=====================
systemctl enable eee_off.service
=====================

It should start automatically after rebooting the machine. In my case it did.
You can check it by typing this in terminal: sudo systemctl status eee_off.service
=====================
