Moving WebFig to another IP address?

Hi,
I am wondering if I can configure WebFig (or the admin setup, including ssh) to a different IP address? Technically it should be possible using multiple IP addresses. Not much of a use-case, just to make it harder for any would-be intruders to find the webpage.

For instance, router IP at 192.168.88.1, subnet 192.168.88.0/24, move the WebFig and ssh to 192.168.88.254 - is it possible?
