First, let's see if you have the right interface.

ip link show |grep enp0s1

if that doesn't show you a line of config, you are specifying
the wrong interface.

ip link show

will show all of them to you.

Second, let's see if something else is doing the configuration:

grep -C1 ifupdown /etc/NetworkManager

(you want this to show managed=false)

ls /etc/systemd/network/

(you would like this to be empty)


Let us know what you find out.
