For what it's worth, you're trying two mutually exclusive commands, as
far as I can see.

NetworkManager automatically configures things as instructed by a DHCP
server, or self-configures a link-local address, or activates a chosen
user-configured network setting (the later may be an option for you, but
you wanted to do stuff by the command line interface, and I'm unfamiliar
with controlling NetworkManager that way).  I've certainly made new
custom settings in the NetworkManager GUI, and chosen them to force
manual changes to my network.

Using an IP command temporarily changes the current operating
parameters, but doesn't change any stored configuration.

NetworkManager's next operation will do what it wants to do, again.
Overriding what you may have temporarily changed.

I would have thought that if you were making temporary changes, this
wouldn't have mattered.  But it sounds like you want to make permanent
changes, despite initially talking about making temporary ones, and
going about it the wrong way.
