How to change van interface via ssh?

Question

SIP

They sent a new scheme for connecting to a sip operator, maybe someone can tell you how to
change it to 10.166.98.246
when you enter ifconfig enp7s0 10.166.98.246 netmask 255.255.255.252 gives "operation not permitted"
Here is the scheme itself that needs to be implemented on the server (we right))
