Think of it this way.

You have your network manager configured (via static or dhcp) to have your
default route pointed somewhere.

NM tries to maintain its configuration so when it notices you've changed
the route at the kernel level it doesn't know it's an admin override and
fixes what it thinks is a broken setup.

On NM based systems instead of using ip route try the nmcli command.

Something like this ought to work:

nmcli conn mod <connection-profile-name> ipv4.gateway
<ip-address-of-gateway>

You can see the present configuration NM thinks it should be with:

nmcli conn show <connection-profile-name>
